The rust library uses the implementations in c/*.c and c/*.S
so I'd say this is intentional and not just a case of a missing exclude=["c/"].

It's also got its own build system separate from being build.rs fodder
and is explicitly documented as a separate distributable.

I think this (and it actually being used thusly) should be sufficient
to build it out as a binary? I don't really see what else would need to
be confirmed here. I'll see what packaging I can come up with.
