As reported by 'scanf' on IRC, the iptables now fails to build because
of a missing <asm/cache.h> header in the kernel headers. The package
directly uses $(LINUX_HEADERS_DIR), which is not correct: this is the
source directory of the kernel, not where they are installed, and in
addition, this directory is empty/does not exist when using external
toolchains.
Instead, we use $(STAGING_DIR)/usr, which contains the kernel headers,
as part of the toolchain headers.

Since a few kernel releases, having 'bc' installed is mandatory to
build the kernel. See commit

of the kernel.
Since this tool is generally available by default in distributions,
and we're unlikely to see version-specific problems with it, we
just check for it to be installed in
support/dependencies/dependencies.sh.

The headers and kernels where changed to XZ format on commit
98b5cc3eb4, but the headers reverted back
to bz2 on the packaging of the toolchain.
This causes double kernel downloads when the versions match, so switch

lttng-tools doesn't require bison or flex, it contains pre-generated
versions of the lexer and parser, so it can build perfectly fine
without bison and flex. We have removed both of these tools from our
mandatory dependencies since a bit of time, the Free Electrons
autobuilders don't have them installed, and the build succeeds.

Using the newly introduced 'eglibc' package, this commit enables the
option of building a toolchain using the eglibc C library in the
Buildroot toolchain backend.
In details, this commit:
* Creates a choice to select uClibc or eglibc in the Buildroot
toolchain backend (in toolchain/toolchain-buildroot/Config.in), and
removes the fact that the Buildroot toolchain backend forcefully
enables uClibc (toolchain/Config.in).
* Creates a BUILDROOT_LIBC variables, which points to the package
implementing the C library (i.e either 'uclibc' or 'eglibc').
* Modifies the gcc-final and gcc-intermediate makefiles to use the
BUILDROOT_LIBC variable instead of hardcoding the use of uclibc.
* Ensures that TLS support is always enabled when building eglibc.

Currently, when we need to do a conditional on the type of C library
used, we need to take into account the three toolchain backends. As we
are going to add eglibc support to the Buildroot toolchain backend, it
would become even uglier, so this patch introduces two new hidden
options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that
exist regardless of the toolchain backend. The entire Buildroot code
base is converted to use those options.
Note that we have intentionally created only one option
(BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are
essentially the same, as far as Buildroot is concerned.

This finally removes the BR2_HAVE_DEVFILES option, that was used to
install/keep development files on target. With the recent migration of
the internal backend to the package infrastructure, we had anyway lost
the ability to build gcc for the target, and install the uClibc
development files on the target.

Several sub-directories of the gcc code base are in fact not needed
for the Buildroot build: libjava/, libgo/ and gcc/testsuite/ being the
biggest ones. Avoiding their extraction saves quite a bit of disk
space, and compensates a bit the fact that we now extract three times
the gcc source code.
This requires changing the 100-uclibc-conf.patch to no longer patch
files from the libjava/ directory, since this directory is no longer
extracted.
