We don't need to point to the inner directory, and this patch changes
that. We used to just because it was easier in the days we had no
central logic for understanding a gcc installation layout.

I like the idea of having "prefix" in the name to match the "--prefix"
option used when building gcc. An updated patch is attached. Is there
anything else I have do change for cmake?

I do intend to make this a runtime option too, but can that be a
follow up patch?
