: ensure make apparmor_parser is cached This change updates parser/Makefile to respect target dependencies and not rebuild apparmor_parser if nothing's changed. The goal is to allow cross-compiled tests #17 to run on a target system without the tests attempting to rebuild the parser. Two changes were made: Generate af_names.h in a script so the script timestamp is compared. * Use FORCE instead of PHONY for libapparmor_re/libapparmor_re.a Changes to list_af_names are intended to exactly replicate the old behavior.
