package/binutils: fix loops relaxation in bare sections

The commit 197b5f9d1c23 ("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.
