That's not parallelizable. Use this instead: 

subdirs: $(foreach DIR,$(SUBDIRS),$(DIR)-subdir)

%-subdir :
        $(MAKE) -C $(subst -subdir,,$@) $(MAKECMDGOALS)

[Louis, 2010/05/21 03:43:21]

Done.

clean: $(foreach DIR,$(SUBDIRS),$(DIR)-subdir)

[Louis, 2010/05/21 03:43:21]

This cannot be parallelized because our build system uses "make clean all" and
accidentally triggers 'make all' in '%-subdir:'.

+                $(MAKE) -C $$i clean; \
