The commit 197b5f9d1c ("package/binutils: fix loops relaxation in
xtensa gas") changed the way loop opcodes are relaxed resulting in build
failures in hand-made assembly code that has loops in sections without
.literal_position pseudo op or equivalent construct. This e.g. breaks
xtensa linux kernel build.
Fix that by adding literal position to the beginning of every section.

Loop relaxation logic in xtensa gas may produce code in which LEND
register doesn't match actual zero overhead loop end. Fix relaxation
code so that it produces a literal or a pair of const16 instructions
with associated relocation record that works correctly in the presence
of other relaxations. This fixes crash in X11 server caused by window
movement.
Loop relaxation has limited of 32K range, this fix removes this
limitation.

This fixes the following build error caused by link-time relaxation
removing copies of literals that reference undefined weak symbols with
PLT entries created due to -rdynamic option passed to g++ link command:
ld: BFD (GNU Binutils) 2.31.1 internal error, aborting at
elf32-xtensa.c:3292 in elf_xtensa_finish_dynamic_sections

>From the release note:
This is a point release over the previous 2.31 version, which was
necessary as a source file was accidentally omitted from that
release.
This release also contains a fix for PR gold/23409 where the gold
linker could end up creating duplicate copies of some symbols.
