When I debug lto1, the missing command line option file generates
a misleading error message and causes ICE:
[...@gnu-34 gcc]$ touch x.s
[...@gnu-34 gcc]$ gcc -c x.s
[...@gnu-34 gcc]$ /export/build/gnu/gcc/build-x86_64-linux/gcc/lto1 -quiet
-dumpbase x.o -mtune=generic -auxbase-strip /tmp/cc0mkdyt.lto.o -O2 -version
@/tmp/ccsQ6Ult -o y.s
