Suppose you had a month in which to reorganise gcc so that it builds

I'm looking for ideas on improving the build time of gcc itself. So
far I have identified two problem areas:
One of the things I've noticed is multilib library targets don't build in
parallel.
I noticed this mostly in libjava, but it applies to others that use the
automake generated bits. Basically the i686 version of the library won't start
building until the x86_64 version has completed due to Makefile lameness.
Building multilibs in parallel would be nice boost for cross-compiler builds.
