quartz everything

[Alexy Khrabrov]

I remember building mono under macports a while ago, and wanting
quartz, no X.  I had to painfully uninstall all gnomy things and
rebuild with no_x11.  Is there a way now to set it globally
beforehand, so no matter what builds, a quartz variant is build and
no_x11 preserved, if possible?  Or, is it possible to have both, and
when building mono, activate only no_x11 for all things which can do
it?
