package/binutils: add binutils 2.26

Browse Source 
- Rebase patches from 2.25 on top of 2.26.
- Use git format for patches
- remove upstreamed xtensa patches

The first patch [1] is needed to be able to build glibc with binutils 2.26 on nios2.
The second from [2] fix an assertion issue with ld.

Subject: [PATCH] sh-conf
Likewise, binutils has no idea about any of these new targets either, so we
fix that up too.. now we're able to actually build a real toolchain for
sh2a_nofpu- and other more ineptly named toolchains (and yes, there are more
inept targets than that one, really. Go look, I promise).

Subject: [PATCH] xtensa: fix signedness of gas relocations
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
directive. Revert this part and add test.
gas/
2016-02-03 Max Filippov <jcmvbkbc@gmail.com>
* config/tc-xtensa.c (md_apply_fix): Mark BFD_RELOC_XTENSA_DIFF*
substitutions for BFD_RELOC_* as unsigned.
gas/testsuite/
2016-02-03 Max Filippov <jcmvbkbc@gmail.com>
* gas/xtensa/all.exp: Add loc to list of xtensa tests.
* gas/xtensa/loc.d: New file: loc test result patterns.
* gas/xtensa/loc.s: New file: loc test.
