What if we changed the top-level machinery such that, instead of using
a directory such as `gcc' to build GCC for the host, it used say
`host-gcc', just like we use `build-libiberty' for libiberty built for
the build machine? Then nothing would be configured/built in the
source tree, except for the top-level, that isn't sensitive to these
matters.
