Well, the first thing was using $ABI directly, and I sent a patch for
that one already.

MULTILIB_WRAPPED_HEADERS will go public, I think. It's kind of nice to
have a single way to list them.

That part is fragile. I'd rather keep both steps encapsulated into two
functions. Especially that if we decide to support wrapping headers
outside /usr/include, the latter part would have to change.
