Don't check undefined symbol for IFUNC reloc
Since x86 elf_*_check_relocs is called after all symbols have been
resolved, there is no need to check undefined symbols for relocations
against IFUNC symbols.
bfd/
* elf32-i386.c (elf_i386_check_relocs): Don't check undefined
symbols for relocations against IFUNC symbols.
* elf64-x86-64.c (elf_x86_64_check_relocs): Likewise.
ld/
* testsuite/ld-i386/i386.exp: Run pr19636-2e-nacl.
* testsuite/ld-i386/pr19636-2e.d: Skip for NaCl targets.
Remove .rel.plt section.
* testsuite/ld-i386/pr19636-2e-nacl.d: New file.
