 This patch fixes the manpage installation dir so it doesn't violate the
 mtree. It also disables the universal variant because AFAICT this port
 does not install anything that's compiled. It also removes a hardcoded
 /usr/X11R6/lib from the ldflags, though I would assume the ldflags and
 build.args can go entirely, since this port doesn't build anything.
