-gdwarf-5 isn't the default yet in GCC 5. So it isn't too urgent. But if
we would like to match the DWARF capabilities of GCC 5 then the
following commits would be nice to have on a (release) branch:
commit 5a19504458d7a4113ef91875a447f4e841df7598
Recognize new DWARF5/GCC5 DW_LANG constants for Fortran 03 and Fortran 08.
commit a2c2acaf15e9cc40bae8a6eebba78aadd3a31b8e
GCC5/DWARFv5 Handle DW_TAG_atomic_type for C11 _Atomic type qualifier.
commit 743649fd80776de922475362bf3ac8b44511bb24
Use GCC5/DWARF5 DW_AT_noreturn to mark functions that don't return normally.
commit 0cfd832fc7d4f1b5633248754dcc75fa90b5475b
Recognize new DWARFv5 C11, C++11 and C++14 DW_LANG constants.
commit e235c3a213b73bf2da20d3c45a60a241139714f0
Merge include/* files from GCC commit 77cab4753.
commit 6ddfe5b4f9644204d5e322a2d026a01190dd38d9
Display DW_LANG_C11 as (C11).
commit 8bc106204c1aedd8c5ffb52453632a632d5484b8
dwarf.c handle new DWARFv5 C11, C++11 and C++14 DW_LANG constants.
commit 0cfd832fc7d4f1b5633248754dcc75fa90b5475b
Recognize new DWARFv5 C11, C++11 and C++14 DW_LANG constants.
Plus the pending patch for gold:

Note that some of those are actually commits for gdb. I hadn't fully
realized binutils and gdb share a git repo (I have separate git checkout
locally). So you would only need the include/ part. Sorry about that. In
the future I will push the include changes separately.
