Add TARGET_SUPPORTS_PIC flag and check that the flag_pic = 2
* config/microblaze/linux.h (TARGET_SUPPORTS_PIC): Define as 1.
* config/microblaze/microblaze.h (TARGET_SUPPORTS_PIC): Define as 1.
* config/microblaze/microblaze.c (microblaze_option_override):
Bail out early for PIC modes when target does not support PIC.
* gcc.dg/20020312-2.c: Define MicroBlaze PIC register
