A couple Makefile-related tweaks

Browse Source 
- Changed --(tool)-tool to --(tool)-path in scripts, this seems to be
  a more common name for this sort of flag.

- Changed BUILDDIR to not have implicit slash, makes Makefile internals
  a bit more readable.

- Fixed some outdated names hidden in less-often used ifdefs.
