Bug #273648 - EAPI 3 - the following condtions must be met:
1. The A variable contains no items.
2. The phase function in question is not in DEFINED_PHASES.
3. None of the phase functions unpack, prepare, configure, compile or install,
   if supported by the EAPI in question and occurring prior to the phase about
   to be executed, are in DEFINED_PHASES.

Thanks to Jonathan Callen <abcd@g.o> for this patch.
