[Xorg] default build options

[Eric Anholt]

I was wondering if we would be interested in switching around default
build options in xorg so that modules that are useless on an OS are not
built.  For example, FreeBSD will never have any use for fbdevhw or
fbdev, but it's still built because of what looks like a policy of
"anything that can build on this architecture (and is therefore usable,
by copying it to an OS that it's usable on) gets built."

Thoughts?
