The GCC build will not touch the source tree unless you configure with
--enable-maintainer-mode (in which case it will automatically try to
re-run some autotools scripts if some of the generated files in the
tree appear to be out of date).

That's completely unnecessary. This doesn't seem like common sense,
but rather creating unnecessary problems for yourself.

Not sure what the [1] refers to, but I think I've said before that you
can just use the recommended versions that are downloaded by the
download_prerequisites script, and not worry about patching anything.

You extracted the tarballs as root.

Either way, it's not a GCC problem.
