# We have to build the base libraries before the other libraries are built,
# and then build the other libraries before the tools are built. Otherwise the
# other libraries and tools would trigger parallel "make -C" builds for the
# base libraries and the other libraries in case of "make -j".
#
# MAKECMDGOALS contains the list of goals, e.g. "clean all". We use
# "foreach" to generate a ";" separated list of "make -C <target>".
# For example the the expansion for "make clean all" is:
#
# $(MAKE) -C $@ [..] clean ;  $(MAKE) -C $@ [...] all ;
#
# This ensures that the commandline targets are serialized and also "make -j"
# works as expected, e.g. "make clean all -j 20".
