To be honest, Bryan, I only care about the fact that the bootstrapped and
non-bootstrapped compilers should be feature/speed compatible, and without
that flag they won't be (as -fomit-frame-pointer speeds the compiler up,
apparently).  If it also makes things byte-for-byte compatible, then all the
better.
