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.
	(elf_x86_64_check_relocs): Likewise.
	(elf_x86_64_relocate_section): Likewise.
	(elf_x86_64_link_setup_gnu_properties): Likewise.
	* elfxx-x86.c (_bfd_x86_elf_merge_gnu_properties): Likewise.
	(_bfd_x86_elf_link_setup_gnu_properties): Likewise.
	(_bfd_elf_linker_x86_set_options): New function.
	* elfxx-x86.h: Include "elf-linker-x86.h".
	(elf_x86_link_hash_table): Add params.

include/

	* bfdlink.h (bfd_link_info): Remove x86-specific linker options.

ld/

	* Makefile.am (ELF_X86_DEPS): Add $(srcdir)/emultempl/elf-x86.em.
	(eelf_i386_sol2.c): Also depend on
	$(srcdir)/emultempl/solaris2-x86.em.
	(eelf_x86_64_sol2.c): Likewise.
	* Makefile.in: Regenerated.
	* emulparams/call_nop.sh: Set x86-specific linker options via
	params.
	* emulparams/cet.sh: Likewise.
	* emulparams/reloc_overflow.sh: Likewise.
	* emulparams/elf32_x86_64.sh (EXTRA_EM_FILE): New.  Set to
	"elf-x86".
	* emulparams/elf_i386.sh: Likewise.
	* emulparams/elf_i386_be.sh: Likewise.
	* emulparams/elf_i386_chaos.sh: Likewise.

	"solaris2-x86".
	* emulparams/elf_x86_64_sol2.sh: Likewise.
	* emultempl/elf-x86.em: New file.
	* emultempl/solaris2-x86.em: Likewise.
	* emultempl/elf32.em (gld${EMULATION_NAME}_before_parse): Don't
	set link_info.call_nop_byte.
