We could factor out the parts used by both projects to a separate file,
and share that one.

Does glibc also have the names in our cpu_supports_info array?  Should
it have them?

What I'm after is making errors and omissions less likely.  Maybe I
just shouldn't worry, it's not like auxv changes *that* often.
