Check run-time R_X86_64_32 relocation overflow
Since elf_x86_64_check_relocs is called after opening all input files,
we can detect dynamic R_X86_64_32 relocation overflow there.

PR ld/19969
* elf64-x86-64.c (check_relocs_failed): New.
(elf_x86_64_need_pic): Moved before elf_x86_64_check_relocs.
Support relocation agaist local symbol. Set check_relocs_failed.
(elf_x86_64_check_relocs): Use elf_x86_64_need_pic. Check
R_X86_64_32 relocation overflow.
(elf_x86_64_relocate_section): Skip if check_relocs failed.
Update one elf_x86_64_need_pic and remove one elf_x86_64_need_pic.
