x86: Move x86-specific linker options to elf_linker_x86_params
Remove x86-specific linker options from bfd_link_info and put them in elf_linker_x86_params. Add _bfd_elf_linker_x86_set_options to pass x86-specific linker options from ld to bfd. bfd/ * elf-linker-x86.h: New file. * elf32-i386.c (elf_i386_convert_load_reloc): Use htab->params to get x86-specific linker options. * elf64-x86-64.c (elf_x86_64_convert_load_reloc): Likewise.
