litecross: separate binutils and gcc build trees

putting them together in one tree only works if they're "sufficiently
close" in version, due to each needing (approximately) its own version
of libiberty and possibly the top-level configure infrastructure.

eventually, I want to stage the installs of binutils and gcc under the
build directory, so that the new binutils can be used from their
staged install paths. leave that refactorization for later; for now,
give gcc the binutils it needs directly out of the binutils build
directories.
