BuildSystem:

BuildSystem:
- changed behavior (which was introduced in r2223) of what MODULE target (phase) is dirtied
  when one of the contrib modules it depends upon is changed; eg: cleaned or build:
        old: MODULE.extract
        new: MODULE.configure
- example of new (corrected) behavior:
        1. svn update brings in a new change on faad2 module which has new version (url)
        2. make
        3. result: faad2 runs the guantlet: fetch->extract->patch->configure->build->install (FXPCBI for short)
        4. result: ffmpeg has a dependency on faad2 and runs: CBI
        5. result: libhb depends on all contrib modules and recompiles all .o and creates .a
        6. result: [no xcode] HandBrakeCLI depends on libhb and recompiles all .o and relinks.
        7. result: [xcode]   HandBrakeCLI and HandBrake may need to be 'cleaned' to force them to recompile as opposed to just relinking.
