toolchain: unbreak glibc on MIPS

Binutils recently updated the ABI version to 5, which broke glibc, as it
refuses to load anything > 3. Upstream reverted the ABI version update,
so backport the commit.

Fixes the following error on boot:

/bin/sh: error while loading shared libraries: /lib/libcrypt.so.1: ELF file ABI version invalid
[    0.920077] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00
[    0.920077]
[    0.929450] Rebooting in 1 seconds..

Subject: [PATCH] MIPS/BFD: Remove EI_ABIVERSION 5 allocation for PT_GNU_STACK
support
Revert commit 17733f5be961 ("Increment the ABIVERSION to 5 for MIPS
objects with non-executable stacks.") and remove EI_ABIVERSION 5
allocation for PT_GNU_STACK support, which has not made it to glibc
and will be reassigned.
bfd/
* bfd/elfxx-mips.c (_bfd_mips_post_process_headers): Revert
2016-02-23 change and remove EI_ABIVERSION 5 support.
