Updated support for MacOS/X Server, OpenStep, and NextStep. Added 'distclean' target which removes config.mak & volatile.h in addition to other files removed by 'clean'.  Added missing .PHONY:win32vc. No longer duplicates platform descriptions from mk/common.mak.  Now directly uses $(DESCRIPTION.platform) macros from mk/common.mak instead.
