Reset x86 Linux targets to not compressing debug sections by default. Enable compression of debug sections by default in the linker, if so configured.
PR gas/19109
. * configure.ac: Note the 'none' is an acceptable argument to
--enable-compressed-debug-sections.
* configure: Regenerate.
gas * configure.ac: Restore --enable-compressed-debug-sections.
Do not enable compressed debug sections by default for x86 Linux
targets.
* configure: Regenerate.
ld * configure.ac: Add --enable-compressed-debug-sections.
* configure: Regenerate.
* config.in: Regenerate.
* ld.texinfo: Document how to determine the default action for
debug sections.
* ldmain.c (main): If DEFAULT_FLAG_COMPRESS_DEBUG is defined then
set the compress_debug field of the link_info structure to
zlib-gabi.
* lexsup.c (elf_static_list_options): Output the default setting
for the --compress-debug-sections option.
* NEWS: Mention the new configure option.
