# architecture-specific flags and dependencies. Remember to do have actions
# for "archclean" and "archdep" for cleaning up and making dependencies for
# this architecture
#
# Note that top level Makefile automagically builds dependencies for SUBDIRS
# but does not automagically clean SUBDIRS. Therefore "archclean" should clean
# up all, "archdep" does nothing on added SUBDIRS.
