I have the same bootstrap error on sparc-sun-solaris2.10.  Your patch does
not fix it for me.  It moves the error to another line:

.../libgcc/../gcc/libgcc2.c: In function '__fixunssfdi':
.../libgcc/../gcc/libgcc2.c:1348: internal compiler error: in
	simplify_subreg, at simplify-rtx.c:4674

Try:

cc1 -fpreprocessed libgcc2.i -quiet -dumpbase libgcc2.c -mcpu=v9
-auxbase-strip _fixunssfdi.o -g -g -g -O2 -O2 -O2 -W -Wall -Wwrite-strings
-Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -version
-fkeep-inline-functions -fPIC -o libgcc2.s
