There's still a bit of code in the s/* m/* files and Makefile.in that
deals with LIBX10_SYSTEM and LIBX10_MACHINE.
Hopefully most of it will disappear after we desupport some platforms.
But there's also oldXMenu/X10.h. Is that still relevant?
Is oldXMenu still used?

It will allow us to get rid of some code in xterm.[ch] and xfns.c, so
it seems worth doing.
How about X11R4, is that still worth supporting?
