Package: dpkg-dev Followup-For: Bug #985980 A space-separated list of enabled features may be useful on its own, and would not increase the complexity in Makefiles.
features := $(shell dpkg-buildflags --enabled-features optimize) ifneq (,$(filter lto,$(features))) ... endif ifneq (,$(filter pgo,$(features))) ... For symetry, a '--disabled-features AREA' option would be nice. For consistency with '--query-features AREA', both should report unknown AREAs with an exit status of 1.
