Decimal floats were introduced circa gcc-4.2 or -4.3, and requires
the floating-point environement fenv.h in the C library.
The uClibc .config file used by crosstool-NG to build uClibc is the
same as used by the internal buildroot mechanism, and explcitly
disables fenv support.
The quick workaround is to simply disable decimal floats in all
crosstool-NG config files.
In the long run, it might be better to check this situation, and/or
add code and/or options in crosstool-NG to handle this (but it is
much more involved, and this workaround is sane).

SUPPORT_LIB_DIR would get resolved to the main buildroot directory for
external toolchains without C++ support, as:
- gcc -print-file-name=<nonexisting-file> returns <nonexisting-file>
- readlink -f <nonexisting-file> returns $PWD/<nonexisting-file>
So fix it by ensuring output of gcc -print-file-name actually exists
before using it.

Sourcery CodeBench toolchain) and e1f0804cc (external-toolchain: add

copy_toolchain_lib_root, but ctng wasn't updated so libraries weren't

In order to use locale support on a Linux system, you need locale data
to be present:
* on a (e)glibc based system, this data is typically in the
/usr/lib/locale/locale-archive file, which can be created and
extended using the localedef program
* on an uClibc based system, the set of supported locales is defined
at build time by an uClibc configuration option.
This patch implements generating locale data for the following cases:
* Internal toolchain
* External toolchain based on (e)glibc. uClibc external toolchains
are not supported, because with uClibc, the set of supported
locales is defined at build time. CodeSourcery and Linaro
toolchains have been tested, Crosstool-NG toolchains are believed
to work properly as well.
* Toolchains built using the Crosstool-NG backend, but only (e)glibc
toolchains.
This feature was runtime tested with internal uClibc toolchain,
CodeSourcery ARM toolchain and Linaro ARM toolchain, thanks to a
simple C program that shows the data and a gettext translated message.
Note that this option differs from the "purge locales" option, which
is responsible for removing translation files and other locale stuff
installed by packages. At some point in the future, we may want to
clarify the respective roles of those options.

When the crosstool-ng backend is used, host-gawk is built as a
dependency of the crosstool-ng package, and therefore an host 'gawk'
binary is installed in $(HOST_DIR).
When the target gdb package is also selected, this unfortunately leads
to a build failure, as reported on
http://buildroot.humanoidz.org/results/f19c0499d08212d8b5100fa9434e1197092957db/build-end.log.
The problem is that the ./configure of gdb detects gawk in the PATH,
but at compile time, it fails to find gawk. This is due to the fact
that the gdb compilation process is started without the correct path.
This patch fixes this by passing $(TARGET_MAKE_ENV) in the environment
of the gdb compilation process.
A better fix would be to switch gdb to the AUTOTARGETS infrastructure
in the future.

Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.
Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.

Quite useful for samba for example so we can use interfaces=eth0 statements in
