description:
Start implementing the new style libgcc "mknative" converter which generates
BSD makefiles to build libgcc.  The goal is to build all functions rather
than managing the set of functions in gnu/lib/libgcc/Makefile.in by hand.

Because of the complexity of the build procedure, I leave not only generated
makefiles but also intermediate, analyzed data so that people can verify that
the conversion is done correctly.
