Canonicalise CT_BUILD and CT_HOST:

- Not only will it give us full-qualified tuples, but it will also ensure
that they are valid tuples (in case of typo with user-provided tuples)
That's way better than trying to rewrite config.sub ourselves...
- use CT_BUILD_PREFIX and CT_BUILD_SUFFIX to call "gcc -dumpmachine"
