This two-patches fixes two corner cases with .cache.mk that have been reported. Neither problem was catastrophic, but certainly several people ran into the problem solved by the first patch (can't build after gcc upgrade) and wasted time debugging, so it's really a good idea to fix. Sorry for the big delay between v2 and v3. I never quite caught up with email after the holidays, but hopefully better late than never... Changes in v3: - Fix as per Masahiro Yamada (move change to main Makefile) - Use "uid 0" as the heuristic instead of install - Do the checking in the main Makefile instead of Kbuild.include Changes in v2: - Don't error if MAKECMDGOALS is blank.
