You havn't tried that, have you?
Last time I did I had to (a) move stuff from $sysroot/usr/... to
$sysroot/ to have compiler and linker find it. Also fixup paths in the
linker scripts (try 'cat /usr/lib64/libc.so'). Nothing really hard but
needs to be done.

If we go add cross-compilers it would be quite useful to also have an
easy ways to cross-build userspace stuff so we are not limited to kernel
cross builds ...
