[PATCH v2 1/1] gdc: define ELFv1 and ELFv2 versions for powerpc

[liushuyu]

From: Zixing Liu <liushuyu...@gmail.com>

gcc/ChangeLog:
        * config/rs6000/rs6000-d.cc: define ELFv1 and ELFv2
          version identifiers according to the target options.

gcc/testsuite/ChangeLog:
        * gdc.dg/ppcabi.d: Add a test to test for code generation
          correctness when using IEEE 128 and new ELFv1 and ELFv2
          identifiers.
