libjava build is broken on SMP

[Mohan Embar]

Tom,

I think the following patch fixes the problem not just for header
files, but anything that depends on a classfile. I'm still doing a
build with this, but wanted to show you it already in case there's
anything blatantly wrong with this. If the build goes okay, I'll
submit it officially.

P.S. I had CVS connection problems so I used Ranjit's makepatch.sh
to generate this (http://ranjitmathew.tripod.com/phartz/gcj/crpatch.html).

Thanks Ranjit!
