Call _bfd_elf_create_ifunc_sections only for ifunc

Browse Source 
Since x86 check_relocs is called after opening all input files, we
need to call _bfd_elf_create_ifunc_sections only for STT_GNU_IFUNC
symbols.

	* elf32-i386.c (elf_i386_check_relocs): Call
	_bfd_elf_create_ifunc_sections only for STT_GNU_IFUNC symbol.
	* elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.
