* Convert binutils to a proper autotargets package
* Add version 2.21 and drop version 2.17
* Hook up packaged binutils for target gcc
* Build tools are on HOST_DIR now so change it
* Move cross/host gcc to HOST_DIR
* Drop kludge from commit 3c77bab2ee
This is fixed in the next commit "gcc: install copies of libgcc,
libstdc++ and libgcj to the sysroot" - tested for arm & x86_64
targets.
* TARGET_CROSS now pointed to HOST_DIR too

The selection of linuxthreads, linuxthreads old or NPTL doesn't make a
lot of sense for external toolchains. So, instead, we :
* Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be
selected by toolchain specific options when thread support is
available. Package needing to test thread support should use this
option.
* Move the none/linuxthreads/linuxthreads old/NPTL selection to
Buildroot internal toolchain configuration.
* Add an option in external toolchain to tell if thread support is
available or not in the external toolchain. We assume that glibc
without threads is not possible, as Ulrich Drepper said in
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html
ffmpeg, dmalloc and openvpn are fixed to use the new
BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix
is no longer used, as the configure script doesn't even understand
this option.

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.

The variable BR2_SYSROOT_STAGING_DESTDIR is no longer used, since now
the prefix for gcc is already set to the correct location.
The variable BR2_SYSROOT_TARGET_DESTDIR was already unused.

The external toolchain and internal toolchain cases both need to use
the --sysroot option, and they have almost identical
LDFLAGS/CFLAGS/CXXFLAGS definition, so we can factorize these
definitions.
Moreover, the --isysroot option is implied by --sysroot so there's no
need to specify both.

This variable, together with the FIXME comment, has been added has
part of Eric Andersen's « Major buildroot facelift, step one » commit
that occured in October 2004.
Since then, no real usage has been made of OPTIMIZE_FOR_CPU, and the
initial intention has probably been lost in the memories of the
implementors.
Therefore, get rid of the variable, and just use $(ARCH) at the two
locations the variable was used.

It seems that there was an intention to add BR2_ENABLE_OPENMP someday,
but it was in June 2007 (commit
c81807a9d7) and since then, nothing
occured. Therefore, get rid of this code, and just pass
--disable-openmp to gettext to keep the current behaviour.

- depending on the BR2_GNU_BUILD_SUFFIX, set the respective EXEEXT, LIBEXT, SHREXT extensions for use on the target.
Thanks to Tom for suplying a diff which implements these.
