Without the -m64, choosing the x86_64 architecture with a Sourcery external
toolchain will result in a 32-bit rootfs.
Also simplified the help text to reflect this change.

The BR2_TARGET_OPTIMIZATION flags were not used by the external
toolchain wrapper, which broke the multilib selection logic of
multilib external toolchains. It also simplifies the compilation of
external programs since all flags are properly passed automatically by
the toolchain wrapper.

Even though MAXARGS 1000 seems large, it wasn't enough for at least
QtWebKit package. This new version does not have any predefined limits.

Many thanks to Thomas for tracing the source of the build error.

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.
With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.
