This breaks WHOPR on darwin. I get lots of warnings like this now:

PASS: gcc.c-torture/execute/ieee/compare-fp-2.c compilation,  -O2 -flto
Setting LD_LIBRARY_PATH to

output is:
/usr/bin/../libexec/gcc/darwin/x86_64/as: Flag option -o has already
been seen!^M

FAIL: gcc.c-torture/execute/ieee/compare-fp-2.c compilation,  -O2 -fwhopr


I am going to go ahead and check in the Mach-O LTO stuff anyway. It
looks like another specs problem.

Ciao!
