Yes, I believe mit-scheme-9.2.tar.gz can only be built if you already
have an executable copy of mit-scheme with which to build it.

Hmm, this would be needed to support cross-compilation for typical
packages, but I suspect that the process is quite a bit different for
mit-scheme.  I'd be very surprised if it was that simple.

For now, I suggest that we focus on getting mit-scheme working on mips
with native compilation.  Later, if someone is motivated, they can look
into what's needed to cross-compile mit-scheme.

      Thanks!
