To be more precise, bootstrapping this way may have worked at some point
in the past: some effort goes into making it work, but keeping it
working is hard, and none of the GCC developers bootstrap that way, so
it often breaks and doesn't get noticed, while bootstrapping from a
parallel directory *is* tested. :)
