E.g. Fedora typically will have gtk devel installed for both biarch arches,
if at all, so gcc build will work there out of the box.  The reason why
Fedora gcc is built with --disable-libjava-multilib is that
we want to package 32-bit binaries/shared libraries in 32-bit packages
and 64-bit binaries/shared libraries in 64-bit packages, so building
32-bit libjava on say x86_64 means just wasting a lot of resources
for something that is not going to be packaged anyway.
