--with-build-config=bootstrap-lto requires --enable-stage1-languages=c,lto.
Why isn't lto added to stage1?

The build-config stuff doesn't look like it could handle that, or can it
simply add lto to STAGE1_LANGUAGES?

If LTO is enabled, I think lto should be added
to STAGE1_LANGUAGES.  Otherwise, stage1 cc1
can't be used for LTO. Sometimes it is easier
to debug stage1 cc1.
