After switching to a two stage gcc solution, there is no longer a need
to do weird things in the uclibc build. We can greatly simplify
UCLIBC_CONFIGURE_CMDS to only do the configuration, and let the
existing UCLIBC_BUILD_CMDS do the build. Note that we have to build
the headers before starting the C library build, otherwise there is a
build failure (probably a uClibc bug).

Currently, the internal toolchain backend does a three stage gcc
build, with the following sequence of builds:
- build gcc-initial
- configure libc, install headers and start files
- build gcc-intermediate
- build libc
- build gcc-final
However, it turns out that this is not necessary, and only a two stage
gcc build is needed. At some point, it was believed that a three stage
gcc build was needed for NPTL based toolchains with old gcc versions,
but even a gcc 4.4 build with a NPTL toolchain works fine.
So, this commit switches the internal toolchain backend to use a two
stage gcc build: just gcc-initial and gcc-final. It does so by:
* Removing the custom dependency of all C libraries build step to
host-gcc-intermediate. Now the C library packages simply have to
depend on host-gcc-initial as a normal dependency (which they
already do), and that's it.
* Build and install both gcc *and* libgcc in
host-gcc-initial. Previously, only gcc was built and installed in
host-gcc-initial. libgcc was only done in host-gcc-intermediate,
but now we need libgcc to build the C library.
* Pass appropriate environment variables to get SSP (Stack Smashing
Protection) to work properly:
- Tell the compiler that the libc will provide the SSP support, by
passing gcc_cv_libc_provides_ssp=yes. In Buildroot, we have
chosen to use the SSP support from the C library instead of the
SSP support from the compiler (this is not changed by this patch
series, it was already the case).
- Tell glibc to *not* build its own programs with SSP support. The
issue is that if glibc detects that the compiler supports
-fstack-protector, then glibc uses it to build a few things with
SSP. However, at this point, the support is not complete (we
only have host-gcc-initial, and the C library is not completely
built). So, we pass libc_cv_ssp=no to tell the C library to not
use SSP support itself. Note that this is not a big loss: only a
few parts of the C library were built with -fstack-protector,
not the entire library.
* A special change is needed for ARC, because its libgcc depends on
the C library, which breaks building libgcc in
host-gcc-initial. This looks like a bug in the ARC compiler, as it
does not obey the inhibit_libc variable which tells the compiler
build process to *not* enable things that depend on the C
library. So for now, in host-gcc-initial, we simply disable the
build of libgmon.a for ARC. It's going to be built as part of
host-gcc-final, so the final compiler will have gmon support.

The configure step of the busybox package performs 'make oldconfig', which
causes the .config file to be updated. Thus, the .config file is more recent
than our stamp file .stamp_kconfig_fixup_done. On a subsequent build, our
dependency rules would kick in, and run the config fixup again, thus
kicking in the package's configure, build and install steps yet once
more, that, ad infinitum.
One solution is to modify kconfig-package to introduce an explicit touch of
the .kconfig_fixup_config_done stamp file, as post-configure hook.
Another solution, implemented by this patch, is to move the oldconfig call
from the package's .mk file to the kconfig-package infrastructure and make
sure it is done as part of the fixup commands. This way, the stamp file will
only be touched once, after the full fixup (including oldconfig) and no
endless rebuilds will occur.

The uclibc-menuconfig command is currently run based on the user-specified
config file, while the fixup of the config file is done afterwards.
However, it makes more sense to do an initial fixup _before_ running
menuconfig, so that the options presented to the user are consistent with
the final configuration.
This patch changes the dependency of the menuconfig target from .config to
.stamp_config_fixup_done to achieve this.

There is no real reason to run uclibc-menuconfig in non-parallel mode,
even though one can neither expect performance benefits from a parallel

In the sequence:
make uclibc-menuconfig
make uclibc-update-config
the freshly configured settings from the menuconfig are lost during the
update-config step. This is because update-config depends on the configure
step, which starts by copying the config file to the build directory.
Instead, stop depending on the configure step from update-config, and
introduce a new stamp file .stamp_config_fixup_done, which applies any
fixups on the .config file.
An alternative solution would be to add a call to UCLIBC_FIXUP_DOT_CONFIG to
the relevant targets instead of depending on a new stamp file. The advantage
of the stamp file, though, is that we avoid redoing the fixup unnecessarily.
Moreover, in the light of the plan to extract the kconfig-specific bits into
a separate kconfig-package infrastructure, the stamp file rules are more
easily moved into such an infrastructure, while the alternative solution
requires the package .mk file to explicitly call the FIXUP rules which may
more easily be forgotten.
No longer depending on the configure step has the added bonus that
'uclibc-update-config' no longer needs the toolchain to be available, which
makes:
make clean uclibc-menuconfig uclibc-update-config
much faster and user-friendly.
Additionally, make sure that 'make clean uclibc-update-config' works
properly, by depending on .stamp_config_fixup_done so that the config file
is present and fixed.

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.

This hidden option is:

* Automatically enabled when an internal uClibc toolchain with NPTL
support is configured. It is left disabled otherwise for internal

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.

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.

This patch removes the sh2, sh3 and sh3eb support, because the user
base is inexistent, and the Linux support for these architectures is
poor. The sh2a support is preserved, because at least one user
expressed interest in this architecture, and is actually using it:

The pread/pwrite handling on the 0.9.33 branch doesn't take into
consideration architectures with an ABI requiring natural alignment for
64bit arguments (afaik ARM EABI, MIPS O32, PPC, SH and Xtensa), causing
havoc.
The issue has been brought with the uClibc developers, but so far a fix is
not available - So lets revert the patches for now as they cause real
issues.

The uClibc options for sh2a is SH2A, not SHA2, and this value should
be used for sh2a, not sh2.

If $(UCLIBC_CONFIG_FILE) is read-only (eg. because Buildroot's
source dir is), the sed fixups to .config fail.
