That's worthwhile, it goes real quick once gcc and glibc are built. Plus
(until recently at least) the published stages always had an out of date gcc
on them.

Twice is pointless :-)
gcc rebuilds itself twice to ensure that the binary is built with the same
version as the result, and verifies that the last two are bit-wise identical.
Then building the toolchain, then building the rest of world gives you exactly
what you hope to get from doing it twice.
