Log Message:
Create a new variable USE_X11_LINKS that controls whether packages that
use buildlink2 and set USE_X11 will use x11-links, or if they will simply
symlink the X11 files directly into ${BUILDLINK_DIR}.  If USE_X11_LINKS is
"YES" (the default), then x11-links is used.  If USE_X11_LINKS is "NO",
then the X11 files are symlinked directly.

There is a choice here between speed and flexibility.  Using x11-links is
faster since you don't need to spend time symlinking all of the X11 files
into ${BUILDLINK_DIR}.  However, if you update your X11 installation, then
the x11-links package will likely be out-of-date.  Conversely, directly
symlinking the X11 files will protect you from changes in your X11
installation when you update, but there is a (small) time penalty to have
to do it for every package that uses X11.
