   9# This file is included by the global makefile so that you can add your own
  10# architecture-specific flags and dependencies. Remember to do have actions
  11# for "archclean" and "archdep" for cleaning up and making dependencies for
  12# this architecture
  13#
  14# Note that top level Makefile automagically builds dependencies for SUBDIRS
  15# but does not automagically clean SUBDIRS. Therefore "archclean" should clean
  16# up all, "archdep" does nothing on added SUBDIRS.
