Following the changes to TARGET_CC/TARGET_CXX to include the --sysroot
option, these variables not only contain the path to the compiler, but
also the --sysroot option. For that reason, we cannot anymore just use
"test -x" to test for the compiler presence. Instead, we see if
$(TARGET_CC) -v and $(TARGET_CXX) -v return a zero status.
Moreover, --sysroot now needs to be filtered out of $(TARGET_CC) and
not $(TARGET_CFLAGS) when asking the toolchain for its original
sysroot and arch sysroot.

The external toolchain and internal toolchain cases both need to use

Until now, the function copy_toolchain_lib_root was copying a given
library to the target filesystem by assuming that it should be at the
same place it was in the toolchain sysroot.
However, with Buildroot hiding libstdc++ in
/usr/<target-name>/lib(64), this isn't correct, and it is probably
safer not to rely on the toolchain organization anyway.
Therefore :
* Instead of having a single EXTERNAL_LIBS variable, we now have
LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS, which respectively
list the libraries that should be copied to /lib and /usr/lib. As
of today, only libstdc++ is part of the second list.
* The copy_toolchain_lib_root takes another argument, which is the
destination directory of the library, relative to $(TARGET_DIR)

For the detection of the ARCH_SYSROOT_DIR (which contains the C
library variant specific to the compiler flags), we used to pass only
the -march argument instead of the full TARGET_CFLAGS. This was done
because TARGET_CFLAGS contains --sysroot, and we don't want to tell
here the compiler which sysroot to use, because we're specifically
asking the compiler where the *normal* arch sysroot directory is.
Unfortunately, there are some multilib variants that aren't decided
only based on -march, but also on -msoft-float or other compiler
flags. Therefore, we take the opposite approach: pass the full
TARGET_CFLAGS, from which we have stripped the --sysroot option.
For example, this allows a PowerPC CodeSourcery toolchain, on which
we're using the soft-float multilib variant, to work properly as an
external toolchain.

This commit, based on an idea by Peter Korsgaard, introduces two

* BR2_NEEDS_GETTEXT, which is true as soon as the toolchain doesn't
provide gettext itself (i.e, when the toolchain is uClibc based, be
it an internal or external toolchain)
* BR2_NEEDS_GETTEXT_IF_LOCALE, which is true when the toolchain
doesn't provide gettext *and* locale support has been enabled in
Buildroot.

When using an external toolchain that uses the glibc or eglibc C
libraries, compiling a separate gettext and libintl is not needed and
is even a source of confusion, causing build failures. These build
failures are due to the fact that when libintl is compiled, it
replaces the C library libintl.h by its own, which does #define
gettext libintl_gettext. Then, when packages want to use gettext,
autoconf realize that gettext is available in the C library and
therefore do not add -lintl to the LDFLAGS, causing the build failure
because the program has been compiled to use libintl_gettext but this
function is not available.
Therefore, we should only use gettext if a uClibc internal toolchain
or a uClibc external toolchain. If an external glibc toolchain is
used, gettext shouldn't be used.
In order to implement that, we introduce the BR2_NEEDS_GETTEXT option,
which is hidden to the user, and whose value is computed automatically
from the rest of the configuration.

Multilib toolchains provide different versions of the base libraries
for different architecture variants. For example, the ARM Codesourcery
toolchain provides base libraries for ARMv5 (default), ARMv4t and
Thumb2.
Depending on the -march= argument passed to gcc, the sysroot used by
the compiler is therefore different. This means that the sysroot
location in CROSS-gcc -v cannot be used. Instead, we must use
CROSS-gcc -print-sysroot when available and fall back to the old way
if unavailable.
Moreover, we cannot simply copy the full sysroot as we used to do,
because the sysroot organization of multilib toolchain is more
complicated. In Codesourcery toolchains, we have :
/
etc -- for ARMv5
lib -- for ARMv5
sbin -- for ARMv5
usr -- for ARMv5 (includes headers)
armv4t
etc -- for ARMv4t
lib -- for ARMv4t
sbin -- for ARMv4t
usr -- for ARMv4t (no headers!)
thumb2
etc -- for Thumb2
lib -- for Thumb2
sbin -- for Thumb2
usr -- for Thumb2 (no headers!)
So we have the default ARMv5 architecture variant that is installed in
the main directory, and we have subdirectories for the ARMv4t and
Thumb2 architecture variants.
Copying the full sysroot to the staging directory doesn't work. All
our packages are based on the fact that they should install libraries
in staging/usr/lib. But if ARMv4t is used, the compiler would only
look in staging/armv4t/usr/lib for libraries (even when overriding the
sysroot with the --sysroot option, the multilib compiler suffixes the
sysroot directory with the architecture variant if it matches a
recognized one).
Therefore, we have to copy only the sysroot that we are interested
in. This is rendered a little bit complicated by the fact that the
armv4t and thumb2 sysroot do not contain the headers since they are
shared with the armv5 sysroot.
So, this patch :
* Modifies how we compute SYSROOT_DIR in order to use -print-sysroot
if it exists. SYSROOT_DIR contains the location of the main sysroot
directory, i.e the sysroot for the default architecture variant.
* Defines ARCH_SUBDIR as the subdirectory in the main sysroot for the
currently selected architecture variant (in our case, it can be
".", "armv4t" or "thumb2"). ARCH_SYSROOT_DIR is defined as the full
path to the sysroot of the currently selected architecture variant.
* Modifies copy_toolchain_lib_root (which copies a library to the
target/ directory) so that libraries are taken from
ARCH_SYSROOT_DIR instead of SYSROOT_DIR. This ensures that
libraries for the correct architecture variant are properly copied
to the target.
* Modifies copy_toolchain_sysroot (which copies the sysroot to the
staging/ directory), so that it copies the contents of
ARCH_SYSROOT_DIR, and if needed, adds the headers from the main
sysroot directory and a symbolic link (armv4t -> . or thumb2 -> .)
to make the compiler believe that its sysroot is really in armv4t/
or thumb2/.
Tested with Codesourcery 2009q1 ARM toolchain, Crosstool-NG ARM glibc
and ARM uClibc toolchains.

The copy_toolchain_lib_root function was making the assumption that
all libraries were stored inside the /lib directory of the sysroot
directory. However, this isn't true for certain toolchains,
particularly for the libstdc++ library.
The function is therefore reworked to find the library and its related
symlink either in /lib or /usr/lib in the sysroot, and copies it at
the same location in the target directory.
