Those defconfigs rely on gcc 4.3.x, which was said to be the only gcc
version that was producing a working kernel. Since we have removed gcc
4.3.x, those defconfigs no longer build. Also, the kernel being used
in these defconfigs was 2.6.32, but there is a "new" 2.6.39 kernel
available from the lpclinux.com git repository, which maybe works fine
with more recent compilers.
However, those defconfigs were contributed by Alexandre Belloni, who
no longer has access to the hardware, so we have no way to verify that
a compiler update + kernel update actually works.
Therefore, we simply remove those defconfigs.

Since commit 2a5cf5e (check kernel headers version), we also need to
specify the series of the custom kernel headers version.
The defconfigs file that define such a custom kernel headers version
now fail to build.
Add the required _AT_LEAST_X_Y options to those config files. Done with
this (convoluted but very fast, uch faster ythan manual editing!) rule:
for f in $( git grep -l BR2_DEFAULT_KERNEL_VERSION=\"3 ); do
grep -E '^BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_' "${f}" >/dev/null && continue
sed -r -e '/^(BR2_DEFAULT_KERNEL_VERSION="3\.([[:digit:]]+).*")$/s//\1\nBR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_3_\2=y/' "${f}"
done
Only kernels >= 3.0 need those options in the defconfig, since the
default for 2.6.x kernels is correct (selects _AT_LEAST_2_6), and
the default is not saved in a defconfig.

at91sam9260pf.h was not used anywhere, and it was unsufficient to add

Those are not associated with any specific hardware system (PC or

require the build of a JFFS2 filesystem, very uncommon on PC systems,
seems to indicate that those configurations are not really being used

It would make more sense to have a qemu_i388_defconfig (building a

The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.
This patch therefore removes the shared configuration cache

This patch modifies current toolchain build sequence so that
NPTL enabled toolchain can be built. The new sequence works
well with linuxthreads as well.
It introduces a new pass for gcc cross compilation. The new
sequence is binutils->gcc-initial->linux-headers -> uclibc-configured
(some cheats to generate phony shared libc.so and libm.o)
-> gcc-intermediate(with shared lib support) -> uclibc -> gcc-final
I also added a new sample config arm_nptl_toolchain_defconfig which
builds the toolchain and busybox.
I have only tried it on arm. However it should work for other
architectures which support NPTL on uclibc e.g. mips, sh, x86, ppc, x86_64

Supporting multilib is much more than just passing --enable-multilib
to gcc. You have to actually build the C library several times (once
for each multilib variant you want to support in your toolchain), and
to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it
know the set of multilib variants you're interested in.
Since we'll probably never support multilib toolchains in Buildroot,
just get rid of this BR2_ENABLE_MULTILIB option.
