The very next release of XFree86 is supposed to be cross-buildable, so
at some point, we'll want to support all that in "xsrc". I gather you
just have to add "-U -M ${DESTDIR}/METALOG" to the install flags to
generate the metalog, but the "pax" man page, as of NetBSD 1.6K,
doesn't yield any clue as to how to use that feature.
