New Revision: 278965
URL: https://svnweb.freebsd.org/changeset/base/278965

Log:
  Restore the ability to use clang as an external compiler. This was
  inadvertently removed when support for external GCC was added.
  
  Deprecate XFLAGS in favour of the newer XCFLAGS/XCXXFLAGS.
  
  Tested with:	make universe, make CROSS_COMPILER_PREFIX=/usr/bin/ buildworld
  Reviewed by:	imp, bapt
