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.
