3.2 bootstrap failure building sparcv7/libjava on sparcv9-sun-solaris2.8

[Brad Lucier]

After trying to bootstrap today's 3.2 CVS sources with

/bin/rm -rf * ; env CC='gcc -m64 -mcpu=ultrasparc' ../configure --prefix=/home/c/lucier/local/gcc-test sparcv9-sun-solaris2.8 ; make -j 8 STAGE1_CFLAGS='-O2 -g' bootstrap > & build.log && ( make -j 8 -k check > & check.log ; make mail-report-with-warnings.log ; ./mail-report-with-warnings.log ) &

bootstrap fails with

The real problem here is that gcjh should never be invoked on Class.
Class.h is not automatically generated, but hand maintained.  I saw
this problem arise after Mark's build speed-up patch went in, but I
still haven't had a chance to investigate.

Perhaps I should have said that after the parallel build failed, I
did "make bootstrap >>& build.log" to get this clean error message.

I finally got around to looking at this.
I'm checking in the appended patch to the trunk and the branch.
