Re: compress .gnu.debuglto_.debug_* sections if requested
Enable zlib-gnu compression for .gnu.debuglto_.debug_*. This differs
from zlib-gnu for .debug_* where the name is changed to .zdebug_*.
The name change isn't really needed.
bfd/
* elf.c (elf_fake_sections): Replace "." with ".z" in debug
section names only when name was ".d*", ie. ".debug_*".
(_bfd_elf_assign_file_positions_for_non_load): Likewise.
gas/
* write.c (compress_debug): Compress .gnu.debuglto_.debug_*
for zlib-gnu too. Compress .gnu.linkonce.wi.*.
