Thanks, I haven't tried this yet, but it looks promising!

For the record, right now I use a GNUmakefile (which takes precedence over
the Makefile) in the build directory containing e.g.

MAKEARGS = ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi-

MAKEFLAGS += --no-print-directory

.PHONY: all $(MAKECMDGOALS)

all := $(filter-out all Makefile,$(MAKECMDGOALS))

all:
$(MAKE) $(MAKEARGS) $(all) -f Makefile

Makefile:;

$(all) %/: all
@:

Gr{oetje,eeting}s,
