rs6000.c (rs6000_override_options): Convert to tartet_flags_explicit. 

* config/rs6000/rs6000.c (rs6000_override_options): Convert to
        tartet_flags_explicit.
        * config/rs6000/rs6000.h (MASK_MULTIPLE_SET, MASK_STRING_SET): Delete.
        Compact target_flags bits.
        (TARGET_MULTIPLE_SET, TARGET_STRING_SET): Delete.
        (TARGET_SWITCHES): Delete references to *_SET flags.
