I'm seeing a crash building on sparc-sun-solaris2.11 that may be due
to this change. The crash occurs in stage 1, the first time the newly
built compiler is used.
./xgcc -B./ -B/var/gcc/iant/install/sparc-sun-solaris2.11/bin/
-isystem /var/gcc/iant/install/sparc-sun-solaris2.11/include -isystem
/var/gcc/iant/install/sparc-sun-solaris2.11/sys-include
-L/var/gcc/iant/bootstrap/gcc/../ld -xc -nostdinc /dev/null -S -o
/dev/null -fself-test=../../gcc/gcc/testsuite/selftests
