Log Message:
Also accept xemacs-nox11 in DEPENDS.  Someone should eventually work the
magic of buildlink here, but in the meantime, there's not much point in
having an xemacs-nox11 without allowing it to install the packages.

(Actually, should xemacs-nox11 become xemacs with PKG_OPTIONS.xemacs without
`x11'?

Which way are we going with these things?)
