mainline stage1 compiler never completes on sparcv9-sun-solaris2.8

[Brad Lucier]

With this configure and build command

#/bin/tcsh
/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='-O0 -g' bootstrap > & build.log && ( make -j 8 -k check > & check.log ; make mail-report-with-warnings.log ; ./mail-report-with-warnings.log )

the stage1 compiler never completes when trying to compile something;
the build log is at
