cf3854a419 toolchain-external: remove non-existent mips-sf musl toolchains
Since 1.1.6, the mips softfloat toolchains are merged into the mips
toolchain using multilib. Our external toolchain infrastructure copies
the correct version to the target depending on the BR2_SOFT_FLOAT
option.

22a59e1bc2 toolchain-external: fix rebuild/reinstall for Linaro toolchains
For Linaro toolchains, a special post install staging hook is used to
create two symlinks needed for the dynamic loader to find the
libraries. However, the way the link is created prevents a 'make
toolchain-external-reinstall' from succeeding, because the symlink
already exists and points to a directory:

ln -sf . /home/thomas/projets/outputs/training/target/lib/arm-linux-gnueabihf
ln: '/home/thomas/projets/outputs/training/target/lib/arm-linux-gnueabihf/.': cannot overwrite directory

This commit adjust the hook to pass the '-n' option so that the link
name is treated as a normal file if it is a symbolic link to a
directory.

cd3c00fbc0 toolchain-external: mark Synopsys toolchain as broken
This uClibc toolchain does not provide an appropriate uClibc
configuration for Buildroot: missing IPv6, missing nsl stub, missing
program invocation, etc. Therefore, we mark it as broken, waiting for
a new upstream release of a new toolchain.

We keep around the toolchain-external Synopsys code anyway, since it
will most likely be identical for the new toolchain version. However,
we remove all the quirks that were introduced to start work around
issues related to this toolchain.

Normally we'd deprecate them, but:

fb5cbf3198 toolchain: fix installing gconv libs with multi-arch toolchain
For a multi-arch toolchain, gconv modules are in a sub-directory named
after the machine gcc targets. This is the case, for example, for the
Linaro ARM 2014.09 toolchain, which has the gconv modules in (relative
to the sysroot):
    /usr/lib/arm-linux-gnueabihf/gconv

while the Sourcery CodeBench ARM 2014.05 (non-multi-arch) has them in:
    /usr/lib/gconv

So, to catter for both cases, search both paths. We want to favour the
machine-specific gconv modules over potentially existing "generic" ones,
so we first search that (if it exists) and fallback to looking in the
generic location.

defb965893 toolchain/external: do not accept distro-class toolchains
Distro toolchains, i.ie. toolchains coing with distributions, will
almost invariably be unsuitable for use with Buildroot:
  - they are mostly non-relocatable;
  - their sysroot is tainted with a lot of extra libraries.

Especially, the toolchains coming with Ubuntu (really, all the Debian
familly of distros) are configured with --sysroot=/ which makes them
non-relocatable, and they already contain quite some libraries that
conflict (in any combination of version, API or ABI) with what Buildroot
wants to build (i.e. extra libraries, some not even present in
Buildroot...) but also their mere preence when Buildroot does not expect
them to be already built (so that a package would enable features when
it should not).

So, try to detect those toolchains and black-list them; inform the user
that the toolchain is unusable for the reasons mentioned above.

1c51a80a7f toolchain/helpers: add check for mandatory uClibc options
We currently only check that the Buildroot configuration matches what is
available in the toolchain.

Since we're going to remove the check for LFS and make it a mandatory
feature, we will lose the corresponding buildroot option, so we won't be
able to use check_uclibc_feature as-is.

Introduce a magic value passed as the buildroot option name to recognise
checks for mandatory uclibc options that do not have a corresponding
option in buildroot.

If the buildroot option name is empty then the check is against a
mandatory uclibc option.

If a mandatory uclibc option is missing we reject the toolchain as being
unusable by buildroot.

23ecfd04e6 toolchain-external: fix support for non-ADI Blackfin external toolchains
The computation of TOOLCHAIN_EXTERNAL_BIN has a special case for
Blackfin, where it's set to
$(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/$(TOOLCHAIN_EXTERNAL_PREFIX)/bin
instead of $(TOOLCHAIN_EXTERNAL_INSTALL_DIR)/bin for other
architectures.

However, this is actually only true for Analog Devices pre-built
toolchains. Other Blackfin external toolchains (such as ones built by
Buildroot) do not have this special organization.

Therefore, in order to make those non-ADI Blackfin toolchains work, we
need to change the condition from BR2_bfin to testing specifically for
the ADI toolchains.

814f63ec32 toolchain: add link-time-optimization support
Add a new option BR2_GCC_ENABLE_LTO that builds gcc and binutils with
LTO support.

Individual packages still have to enable LTO explicitly by passing '-flto' to
GCC, which passes it on to the linker. This option does not add that flag
globally. Some packages detect if the compiler supports LTO and enable the flag
if it does.

To support LTO, ar and ranlib must be called with an argument which triggers the
usage of the LTO plugin. Since GCC doesn't call these tools itself, it instead
provides wrappers for ar and ranlib that pass the LTO arguments. This way
existing Makefiles don't need to be changed for LTO support. However, these
wrappers are called <tuple>-gcc-ar which matches the pattern to link to the
buildroot wrapper in the external toolchain logic. So the external toolchain
logic is updated to provide the correct symlink.

[Thomas:
  - Add a separate BR2_BINUTILS_ENABLE_LTO option to enable LTO
    support in binutils. This is a blind option, selected by
    BR2_GCC_ENABLE_LTO. It just avoids having binutils.mk poke
    directly into gcc Config.in options.
  - Remove the check on the AVR32 special gcc version, which we don't
    support anymore.
  - Adapt the help text of the LTO Config.in option to no longer
    mention "Since version 4.5", since we only support gcc >= 4.5 in
    Buildroot anyway.
  - Fix typo in toolchain-external.mk comment.]

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.

As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.

This also helps preparing the addition of other options to select
shared, shared+static or just static.

Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

5aa205eba4 toolchain-external: instrument wrapper to warn about unsafe paths
The CodeSourcery toolchains have a very interesting feature: they warn
the user when an unsafe header or library path is used, i.e a path
that will lead host headers or libraries to leak into the build.

This commit adds a similar functionality into our external toolchain
wrapper, so that it can be used with all external toolchains, and can
also be tuned as needed. By default, the external toolchain wrapper
now gives warnings such as:

  arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-I /usr/foo'
  arm-linux-gcc: WARNING: unsafe header/library path used in cross-compilation: '-L /usr/bleh'

but the compilation continues successfully. One can then easily grep
in his build log to search for occurences of this message.

Optionally, if BR_COMPILER_PARANOID_UNSAFE_PATH is defined in the
environment to a non empty value, the external wrapper will instead
error out and abort the compilation.

3e0440407a toolchain/external: fix building the wrapper on MIPS
Some crazy folks use MIPS machines as build machines. ;-)

On MIPS, the only acceptable hash-style is 'sysv', because the MIPS ABI
defines that the GOT ordering to be the same as the symbols ordering,
while GNU hash requires symbols to be sorted by their hash.

Looking at binutils' code, it seems that only MIPS suffers from that
limitation.

Currently, we force the toolchain wrapper to be linked with both hash
styles, which breaks on MIPS.

So, fix that by singling out MIPS, and use sysv in that case, and both
otherwise.

cce0add500 toolchain: do not allow locale generation when locale support is not available
When the C library being used is uClibc, the locale support can be
disabled. In this case, it does not make sense to show the "Generate
locales" option.

bd0ffe2206 toolchain: do not allow BR2_GENERATE_LOCALE with musl
Generating locales is possible in two situations:

 - With the internal toolchain backend, when the uClibc library is
   used. With uClibc, locales are generated at build time of the C
   library, so with uClibc it's only possible with the internal
   toolchain backend.

 - With either the internal or external toolchain backend when the
   glibc library is used. With glibc, locales can be generated
   afterwards, using the host-localedef utility.

Until we had the musl C library supported in the internal toolchain
backend, the condition: BR2_TOOLCHAIN_BUILDROOT ||
BR2_TOOLCHAIN_USES_GLIBC was correct to capture the above two
situations. Now that we have musl support in the internal toolchain
backend, then BR2_TOOLCHAIN_BUILDROOT is incorrect, and we should use
BR2_TOOLCHAIN_BUILDROOT_UCLIBC instead.

Basic locale support in musl has appeared in musl 1.1.4, but we are
not yet capable of generating the locale files for musl.

28bca1cef5 toolchain-external: update Linaro toolchains
Bump the ARM, ARMeb and AArch64 Linaro toolchains from 14.08 to
14.09. We can't bump to 14.10, because they completely changed the
toolchains and they are now completely broken: they switched from
Crosstool-NG to a new build tool to generate the toolchain, and now
the sysroot handling is completely borked.

29f680644a toolchain-external: use BR2_ARM_CPU_ARM* options
Refactor the toolchain-external Config.in file to use the
BR2_ARM_CPU_ARM*. All of the changes are purely mechanical, except for
the Arago ARMv5 toolchain: it had a 'depends on BR2_GCC_TARGET_ARCH !=
"armv5t"', but armv5t was not a possible value for
BR2_GCC_TARGET_ARCH. Since the toolchain is ARMv5TE, the only ARM
architectures we need to exclude are ARMv4 and ARMv4T.
