elf/x86-64: Adjust relocation for PE/x86-64 inputs
PE linker calls _bfd_relocate_contents to resolve relocation, instead of
bfd_perform_relocation. But ELF linker calls bfd_perform_relocation, not
_bfd_relocate_contents. When linking PE/x86-64 inputs to generate ELF
output, we need to adjust PE/x86-64 relocations in bfd_perform_relocation.
Enable PE/x86-64 in bfd together with PEI/x86-64. Update run_ld_link_tests
to handle bzip2 binary inputs.
