What happens if you run it on an older machine, or as BE or 32-bit,
or with vectors disabled?

Yeah.
I'd still like to see these headers moved into some subdir (both in
the source tree and in the installed headers tree), to reduce clutter,
but I understand it's not trivial to do.

This is okay for trunk. Thanks!

(Your mail client wrapped this).
Write this on a separate line? Like
extra_headers="${extra_headers} htmintrin.h htmxlintrin.h bmi2intrin.h"
(You cannot use += here, pity).
