Fix segfault in ARC linker when generating got entries for local symbols.
bfd * arc-got.h (relocate_fix_got_relocs_for_got_info): Handle the case
where there's no elf_link_hash_entry while processing GOT_NORMAL got
entries.
ld * testsuite/ld-arc/got-01.d: New file.
* testsuite/ld-arc/got-01.s: New file.
