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.
