# MULTIDIRS is non-empty for the cpu top level Makefile (eg: newlib/Makefile)

# MULTISUBDIR is non-empty in each cpu subdirectory's Makefile
# (eg: newlib/h8300h/Makefile) and is the installed subdirectory name with
# a trailing '/'.
# MULTIDO is used for targets like all, install, and check where
# $(FLAGS_TO_PASS) augmented with the subdir's compiler option is needed.
# MULTICLEAN is used for the *clean targets.
#
# ??? It is possible to merge MULTIDO and MULTICLEAN into one. They are
# currently kept separate because we don't want the *clean targets to require
# the existence of the compiler (which MULTIDO currently requires) and
# therefore we'd have to record the directory options as well as names
# (currently we just record the names and use --print-multi-lib to get the
