PowerPC64 defines .TOC. rather than _GLOBAL_OFFSET_TABLE_, and what's more, doesn't define it at all unless referenced. For ELFv1 ABI the symbol isn't normally referenced, so modify the test to accept .TOC. as a variant of _GLOBAL_OFFSET_TABLE_ and 0 or 1 occurrences. copy_test_relro as written doesn't need copy relocs on PowerPC64. PowerPC64 is always PIC. So, modify copy_test_relro to test that the existing vars are in fact read-only directly by deliberately causing a sigsegv, and add another couple of vars that do cause copy relocs even when PIC. * testsuite/ver_test_8.sh: Accept .TOC. in lieu of _GLOBAL_OFFSET_TABLE_. Allow zero count. * testsuite/copy_test_relro_1.cc (c, q): New vars. * testsuite/copy_test_relro.cc: Rewrite to test read-only status of variables directly. Reference new vars in read-only data.
