Hmm. Some things that help with this for me are to:
1) Compile with -j12 (or lower, depending on your hardware spec)
2) Compile with "cd compiler && make stage=2" to only build the stage
2 compiler (if this isn't already happening). Make sure the stage 1
compiler is built with optimisations! (I use the stage2devel
configuration, which already does this)

This reduces compile times to a few minutes for me. Still tedious, but
not too bad.

Hope that helps,
