The '?' that is used in the sed expression that determines MK_ARCH

suggested by the OpenBSD re_format(7) man page.

Considering that it's not the first time someone breaks this by making
it non-POSIX, can you add a comment just above with a link to the
re_format(7) man page so people are at least more aware than they are
right now?
Thanks!
