> First, we highly recommend that GCC be built into a separate directory
> from the sources which does not reside within the source tree.
> This is how we generally build GCC; building where srcdir == objdir
> should still work, but doesn't get extensive testing; building where
> objdir is a subdirectory of srcdir is unsupported.
