The question is how far we want to go, since a real multilib toolchain would
require multilib-versions of not only libgcc but also (at least) glibc
and libstdc++.
The linaro toolchain is currently very much usable to build a pre-v7
kernel and anything that uses -ffreestanding, and IMHO we should
try to keep it that way.
Would there be anything that we might want to build besides u-boot that
requires an matching libgcc but not also an matching glibc?
