H.J. Lu 8c0546e928 elf/x86-64: Subtract __ImageBase for R_AMD64_IMAGEBASE ... When linking Windows x86-64 relocatable object files to generate x86-64 ELF executable, we need to subtract __ImageBase, aka __executable_start, for R_AMD64_IMAGEBASE relocation: 1. Add link_info to struct output_elf_obj_tdata to store linker info and _bfd_get_link_info() to retrieve it. 2. Add ldelf_set_output_arch to set up link_info. 3. Add pex64_link_add_symbols to create an indirect reference to __executable_start for __ImageBase to support R_AMD64_IMAGEBASE relocation when adding symbols from Windows x86-64 relocatable object files to generate x86-64 ELF executable. 4. Also subtract __ImageBase for R_AMD64_IMAGEBASE when generating x86-64 ELF executable. bfd/ PR ld/27425 PR ld/27432 * bfd.c (_bfd_get_link_info): New function. * elf-bfd.h (output_elf_obj_tdata): Add link_info.
