Simple solution:
SUBDIRS = a b c d
subdirs:
for $$dir in $(SUBDIRS); do \
cd $$dir && $(MAKE) || exit 1; \
done
Note the "|| exit 1", which terminates the loop.
Now, the problem with the simple solution is that it stops
too early in the case of `make -k'.
So another solution is as follows:
SUBDIRS = a b c d
subdirs: $(SUBDIRS:%=%.subdir)
%.subdir:
cd $* && $(MAKE)
