[PATCH/AARCH64] Fix elfNN_aarch64_howto_from_bfd_reloc for BFD_RELOC_AARCH64_NONE and ILP32

[Andrew Pinski <andrew dot pinski at caviumnetworks dot com>]

Hi,
  The problem here is that the type inside elfNN_aarch64_howto_table
for BFD_RELOC_AARCH64_NONE is 0 since that is the relocation number of
NONE so we return NULL from elfNN_aarch64_howto_from_bfd_reloc but
when really wanted to return a real howto.  This happens with TLS
relaxation code when it is recording a relocation as being none.

This fixes the problem by explicitly checking for
BFD_RELOC_AARCH64_NONE and returning elfNN_aarch64_howto_none.

OK?  Built and tested on aarch64-elf and aarch64-linux-gnu (with a few
extra patches which adds ilp32 support).

Thanks,
Andrew

ChangeLog:
* elfnn-aarch64.c (elfNN_aarch64_howto_from_bfd_reloc): Handle
BFD_RELOC_AARCH64_NONE explicitly.
