This commit bumps make to version 4.0. This version now uses fork(),
so it is no longer available on non-MMU platforms, which consequently
works around:
http://autobuild.buildroot.org/results/2e1/2e1b11ccb501f1ab431c04435be52a6538d035cb/
The glob special options seem to no longer be needed, at least make
4.0 builds fine with both an ARM uClibc toolchain and an ARM glibc
toolchain.

This is only required for uClibc 0.9.31 and this veriosn is only used by
AVR32 so could be safely removed together with AVR32.
Even 0.9.32 builds well in parallel (at least on x86) so IMHO there's no need
in >= 0.9.33, just disable for a particular broken version.

The use of MAKE1 for uClibc dates back 10 years:
commit 8e5fb3fb4a
Author: Eric Andersen <andersen@codepoet.org>
Date: Sat Dec 11 13:01:10 2004 +0000
Add initial BR2_JLEVEL support, with some exceptions for apps that
have broken 'make -j' support
Since that time there were lots of improvements in uClibc that seem to allow
parallel building of libs finally.
Unfortunately uClibc tests have dependences on previously built files,
that's why tests left with MAKE1.

Currently we configure uClibc to use kernel headers from "staging" folder with
KERNEL_HEADERS="$(STAGING_DIR)/usr/include". This path is added to include
search path of uClibc build system in Rules.mak "CFLAGS += -I$(KERNEL_HEADERS)".
At the same time on uClibc installation to "staging" we point to the same
location "$(STAGING_DIR)/usr" (headers effectively go in "usr/include").
So after every installation to "staging" dependences get touched (even though we
copy the same headers every time) and so we may see lots of sources in uClibc
get rebuilt.
This has 2 consequences:
1. Longer build time - becase even on ordinary buildroot build uClibc is built
twice. On "uclibc building" and on "uclibc installation to target".
2. Symbols in libuClibc built initially (that is later installed in
"staging/sysroot") are situated with different offset compared to second build
(later copied in "target"). This happens because as described above only part
of sources get rebuilt and then on final linkage object files are linked in
different order.
And (2) leads to problems on remote rebugging: gdbserver reports offsets that
correspond to pointless assembly in libuClibc on host.
Here's how it looks like.

Add two uClibc 0.9.33.2 patches which fix issues relating to high signal
number handling on MIPS.
The first patch (0056) fixes _NSIG (and as a result __SIGRTMAX) to match
glibc. This fixes GDB on MIPS with uClibc, which cannot handle
__SIGRTMAX == 128 and emits the error:
GDB bug: target.c (gdb_signal_from_host): unrecognized real-time signal
This patch is from uClibc commit 2da958760f79 (MIPS: set _NSIG to
128, not 129. This matches glibc.) and applies without conflicts.
The second patch (0057) fixes the wait status macros to correctly
interpret status 0x007f on MIPS (other arches don't have signal 127).
This patch is from uClibc commit 4a96b9486871 (bits/waitstatus.h:

Add uClibc 0.9.33.2 patch to fix arch specific eventfd definitions,
particularly EFD_NONBLOCK. The definition in sys/eventfd.h was 04000
(0x800), however MIPS uses 0200 (0x80). This resulted in QEMU built for
MIPS hanging at various points until input is received due to a blocking
poll of stdin.
The patch is a backport of uClibc commit fd355bc1dbcb (eventfd.h: Use
new "bits/" scheme for arch-specific flags). The only conflict was minor
in Makefile.in.

Problem is there are no emulation targets and real ARM(7TDMI/720T/740T)
hardware that's capable of running linux (enough memory, having a
memory controller...) is VERY rare and uses very old versions to

As our architecture support expands to a number of architectures that
do not implement NPTL threading, and the number of packages that
depend on NPTL specific features, it has become necessary to be able
to know whether the toolchain has NPTL support or not.
This commit adds a new BR2_TOOLCHAIN_HAS_THREADS_NPTL hidden Config.in
option that allows packages to know whether NPTL is available or not.
This hidden option is:
* Automatically enabled when glibc/eglibc or musl toolchains are
used, either internal or external.
* Automatically enabled when an internal uClibc toolchain with NPTL
support is configured. It is left disabled otherwise for internal
uClibc toolchains.
* Configured according to a visible Config.in option for custom
external uClibc toolchains.

The three typical packages that use .config files in buildroot copy the
config file at different times in the build process:
busybox copies its .config from the post-extract hook.
linux copies its .config in the configure_cmds.
uclibc copies its .config from the post-patch hook.
Copying the .config file from the configure step is the only way to properly
support an OVERRIDE_SRCDIR that does not yet have the .config file, because
the extract and patch steps are skipped in that case.
In a previous patch, the situation was already fixed for busybox. This patch
applies the same fix to uclibc: copy the config file from the configure
step, as linux is doing.

To be able to use top-level parallel make we must not depend in a rule
on the order of evaluation of the prerequisites, so instead of relying
on the left to right ordering of evaluation of the prerequisites add
an explicit rule to describe the dependencies.
We cannot use the pattern rules because they must have the same
dependency for every package, but we need to change the dependencies
depending on $(2)_OVERRIDE_SRCDIR variable value, so we must use a
more flexible way like $(2)_TARGET_% variables.
So add explicit dependencies for the following stamp files:
$(2)_TARGET_EXTRACT
$(2)_TARGET_PATCH
$(2)_TARGET_CONFIGURE
$(2)_TARGET_BUILD
$(2)_TARGET_INSTALL_STAGING
$(2)_TARGET_INSTALL_TARGET
$(2)_TARGET_INSTALL_IMAGES

This commit makes the dependency from the target toolchain explicit.
This way we can buid from command line a package that use
inner-generic-package right after the configuration phase, example:
make clean <package-name>
Also remove TARGETS_ALL because the only purpose was to add toolchain
dependency so it's superseded by this commit.
To prevent circular dependency add the new variable
<pkgname>_ADD_TOOLCHAIN_DEPENDENCY to avoid adding the toolchain
dependency for toolchain packages.
This is also a step forward supporting top-level parallel make.

Currently, the Xtensa architecture uses the "snapshot" version of

pick whatever latest version of uClibc is available at the moment of

This commit replaces that by adding a special Xtensa version, which
points to a well-known Git commit. This is something we should
hopefully be able to remove once the uClibc people realize that doing
a 0.9.34 release would be useful.
