The '?' that is used in the sed expression that determines MK_ARCH is part of the extended regular expression syntax, but the default behaviour of sed as specified by POSIX is to use only basic regular expression syntax. Use the equivalent '{0,1}' instead as suggested by the OpenBSD re_format(7) man page.
