elf: Handle .gnu.debuglto_.debug_* sections
commit 994b25132814f4c2be93ce53a616a74139c4cf3c
Author: H.J. Lu <hjl.tools@gmail.com>
Date: Sun Jan 17 20:01:16 2021 -0800
ld/elf: Ignore section symbols when matching linkonce with comdat
ignored section symbols when comparing symbols in 2 sections. Since all
references to debugging sections are done with section symbols, symbols
in debugging sections are ignored and we fail to match symbols in comdat
debugging sections. Also .gnu.debuglto_.debug_* sections aren't treated
as debugging sections.
1. Treate .gnu.debuglto_.debug_ section as debugging section unless it
is marked with SHF_EXCLUDE.
2. Revert commit 994b2513281 in elf_create_symbuf.
3. Ignore section symbols only when matching non-debugging sections or
linkonce section with comdat section.
