This isn't a "make" in the conventional sense -you're running a shell
command which just happens to be make. The $(shell) command has no
particular error handling features. To get this to work would be a bit
of hassle. e.g. set a flag file if your $(shell) command fails (you'll
have to do that in the $(shell) command itself), then check for that
flag with:

ifneq (,$(wildcard my_error_file)
$(error my build broke)
endif

or something along those lines.
