This is what I was referring too... cross gcc in /opt/poky/ that can
build for multiple targets...

It just builds an installable tarball with the toolchain components
and some other nativesdk components.

Can't really comment on your patch... but I know it would be nice to
generate a cross gcc that supports more than just the target yocto is
building for at the time. For instance, build support for all powerpc
or all x86 targets poky could possibly build for when building
meta-toolchain....
