Syn68k now uses automake for all the Makefiles, but we do enough
things on our own that we're not getting proper dependency tracking
and most likely make clean doesn't work as well as it could.

Syn68k has not been actively worked on for about ten years. A few
mods have been made here and there to keep up with changes in gcc.

Make it so that we can install libsyn68k.a and the .h files
Make so we can build the various debug versions, non-native, etc.
Figure out exactly which variables Makefile.common.in sets, then
get rid of Makefile.common.in
see TODO.variables
figure out what to do concerning bswap
Look into what else from syn68k we can delete
Makefile.common.in
config
Make sure make clean really does a make clean
Make sure we get proper dependencies (if possible)
make sure syn68k builds on a powerpc (either the
old yellow dog linux on sybil, or on Mac OS X on sybil)
non-native
figure out *exactly* which options should be available
via configure
clean the junk out of test (mostly old test results)
build some semi-canonical test results to use for
comparing on other platforms
write-up what is needed to do testing on a real m68k
need a .spec file so we can build syn68k and syn68k-devel
