In one project I use -- though not a "header + main makefile" but
a "main makefile + subordinates" layout --:
# Makefile.am (http://tinyurl.com/dhxfwf)
bin_PROGRAMS =
include bar/Automakefile
include foo/Automakefile
# bar/Automakefile
bin_PROGRAMS += bar
# foo/Automakefile
bin_PROGRAMS += foo
that is, setting all variables ever used to "" before appending to them.
