the eval trick does work, however the variables are then passed in the
environment, not on the command line. I don't think it makes a difference for
GNU autoconf, but it might not be appropriate for other build systems.

No. Doesn't work if the call depends on the loop variable.

Right, but that's needed for stuff like
for p in $(filter-out $(PYTHON_DEFAULT), $(PYTHONS)) \
; do \
dh_auto_configure --builddir=$(CURDIR)/debian/build-$$p \
-- \
$(BARE_CONFIG_FLAGS) \
--disable-ruby \
PYTHON=$$p \
$$(DEB_CFLAGS_MAINT_APPEND=$$($$p-config --includes)
dpkg-buildflags --export=configure)"; \
done
