[AArch64] Use SYMBOL_REFERENCES_LOCAL in one symbol check
For some pc-relative relocations we want to allow them under PIC mode while
a normal global symbol defined in the same dynamic object can still bind
externally through copy relocation. So, we should not allow pc-relative
relocation against such symbol.
SYMBOL_REFERENCES_LOCAL should be used and is more accurate than the original
individual checks.
bfd/
* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Use
SYMBOL_REFERENCES_LOCAL.
ld/
* testsuite/ld-aarch64/aarch64-elf.exp: Update test name
* testsuite/ld-aarch64/pcrel.s: Add new testcases.

warnings.
* testsuite/ld-aarch64/pcrel_pic_defined_local.d: Rename ...
* testsuite/ld-aarch64/pcrel_pic_defined.d: ... to this.
Update expected warnings.
