Thanks. Doing this seems to improve the situation:

#!/usr/bin/make -f
%:
	dh $@

.PHONY: build-arch build-indep
build-arch build-indep:
	dh $@

.PHONY: build
build: build-arch build-indep

However, dh still attempts to build the package twice but this time the
second instances of dh do nothing:

$ fakeroot debian/rules binary
dh binary
   debian/rules build
make[1]: Entering directory '/tmp/y'
dh build-arch
   dh_update_autotools_config -a
   dh_autoreconf -a
   dh_auto_configure -a
   dh_auto_build -a
   dh_auto_test -a
   create-stamp debian/debhelper-build-stamp
dh build-indep
make[1]: Leaving directory '/tmp/y'
   debian/rules build-arch
make[1]: Entering directory '/tmp/y'
dh build-arch
make[1]: Leaving directory '/tmp/y'
   dh_testroot
   dh_prep
   dh_auto_install
   dh_installdocs
   dh_installchangelogs
   dh_perl
   dh_link
   dh_strip_nondeterminism
   dh_compress
   dh_fixperms
   dh_missing
   debian/rules build-indep
make[1]: Entering directory '/tmp/y'
dh build-indep
make[1]: Leaving directory '/tmp/y'
   dh_strip
   dh_makeshlibs
   dh_shlibdeps
   dh_installdeb
   dh_gencontrol
   dh_md5sums
   dh_builddeb
