Add a gas configure option to select the default behaviour for the generation of debug sections - compressed or uncompressed.
PR gas/19109 * configure.ac: Add option --enable-compressed-debug-sections. This sets the default behaviour for compressing debug sections. * as.c (flag_compress_debug): Define and initialise to COMPRESS_DEBUG_GABI_ZLIB if DEFAULT_COMPRESS_DEBUG is set. (show_usage): Indicate whether --no-compress-debug-sections or --compress-debug-sections is the default. * config/tc-i386.c (flag_compress_debug): Delete definition. * doc/as.texinfo (--nocompress-debug-sectionas): Update description. * NEWS: Announce the new feature. * config.in: Regenerate. * configure: Regenerate.
