This is a GC problem, not a libffi problem.  The boehm-gc gctest
program crashes in the same way as every java program; also a libffi
problem wouldn't show itself as a systematic failure of all the
libjava execute tests (most programs never use libffi).

I don't think it is a regression either.  However, that leaves us in
the odd situation where we build a compiler where the -m32 libraries
work and the -m64 ones do not.  This is why I had left it as high
priority.  That said, it isn't clear I'll actually be able to finish
debugging this before the deadline, either.
