Nick Clifton f657f8c4a1 Fix Sparc, s390 and AArch64 targets so that they can handle relocs against ifunc symbols found in note sections. 
Following on from PR 22929, I have found the same problem exists with
  other ifunc supporting targets too.  Plus see this link for the bug
  being reported against the s390x binutils for Fedora rawhide:

     https://bugzilla.redhat.com/show_bug.cgi?id=1553705

  So I am going to check in the patch below which applies the same
  change that H.J. made for the x86_64 target to the other affected
  targets.  (Specifically: S390, AArch64 and Sparc).  Plus it adds a new
  test to the linker testsuite to make sure that this problem stays
  fixed.

bfd	* elf64-s390.c (elf_s390_relocate_section): Move check for
	relocations against non-allocated sections to before the code that
	handles ifunc relocations.
	* elf32-s390.c (elf_s390_relocate_section): Likewise.
	* elfnn-aarch64.c (elfNN_aarch64_final_link_relocate): Treat
	relocs against IFUNC symbols in non-allocated sections as relocs
	against FUNC symbols.
	* elfxx-sparc.c (_bfd_sparc_elf_relocate_section): Likewise.

ld	* testsuite/ld-ifunc/ifuncmod5.s: New test.  Checks that targets
	that support IFUNC symbols can handle relocations against those
	symbols in NOTE sections.
	* testsuite/ld-ifunc/ifuncmod5.d: New file:  Driver for the new
	test.
	* testsuite/ld-ifunc/ifunc.exp: Run the new test.
