I don't think it's critical, and I don't care for rc8, so it's not
timing-sensitive.

Maybe David should do it as part of the "the compiler people changed
the name of the thunks" series anyway, since now I think that
RETPOLINE_CFLAGS test might want to be extended too (to see which
_version_ of the thunks we need to export).

Or maybe we'd just export the damn thunks under both names, just to
allow people to use both versions of the compilers.

Christ, what a mess.

My "let's not warn" is not important, and the thunk naming thing
should be resolved first. Gaah.

So I think letting David worry about it sounds about right.
