<AWT Dev> [macosx] disable X11 toolkit?

[David DeHaven]

I recall discussing removal of the X11 toolkit on Mac OS X...

There's already a JBS issue for it:
https://jbs.oracle.com/bugs/browse/JDK-8003900

Time to pull the trigger?

I did a test run last night with a fairly simple fix that disabled building X11 code, all but a few jtreg tests passed and the failures were unrelated. It would be ideal if I could get this fix in before backporting my fix for jawt_md.h as I'd prefer removing the X11 stuff from that header, though I suppose I could do that first then remove those sections as part of this fix. The build system needs a bit more cleanup before the patch is ready for review though, there were a number of Mac specific items in the makefiles.
