I do like the idea of skipping a lot of time-consuming compiler tests
when building those modules in a full build, but I'm not sure that's
the best way to do it.

Instead of undoing XORG_DEFAULT_OPTIONS and going back to updating every
configure script for every global change I'd rather we introduced into
xorg-macros either an argument to XORG_DEFAULT_OPTIONS to skip the calls
that set up compiler flags or have new macro that's the appropriate
subset of options for modules that don't use the compiler.

For instance, the above is missing XORG_INSTALL, AC_PROG_INSTALL, &
the setup of AM_SILENT_RULES which all are applied in current
XORG_DEFAULT_OPTIONS and are useful for fonts & similar modules.
