s:Thibault:Thibaut: ;)
Minus the C++ issue (libstdc++6-4.7-dev not being M-A: same), multiarch
cross-toolchains are already usable. The gcc patches are based on sid's
gcc-4.7 and can easily be backported to the version currently in wheezy.
I've successfully built armel and armhf cross-compilers in the past, as
well as an amd64 cross-compiler for i386. I've just successfully built a
single-lib powerpc cross-compiler, but since ppc64 libs are not in the
archive, it would probably make sense to have a multilib cross-compiler
with ppc64 support. I'm working on that right now.
