Support compressed debug sections
* configure.ac (gcc_cv_as_compress_debug): Check for assembler
compressed debug support.
(gcc_cv_ld_compress_debug): Check for linker compressed debug
support.
* configure: Regenerate.
* config.in: Regenerate.
* common.opt (compressed_debug_sections): New enum.
(gz, gz=): New options.
* gcc.c (LINK_COMPRESS_DEBUG_SPEC, ASM_COMPRESS_DEBUG_SPEC):
Define.
(LINK_COMMAND_SPEC): Invoke LINK_COMPRESS_DEBUG_SPEC.
(asm_options): Invoke ASM_COMPRESS_DEBUG_SPEC.
* config/darwin.h (LINK_COMMAND_SPEC_A): Invoke
LINK_COMPRESS_DEBUG_SPEC.
* config/i386/djgpp.h (LINK_COMMAND_SPEC): Likewise.
* opts.c (common_handle_option): Handle OPT_gz, OPT_gz_.
* doc/invoke.texi (Option Summary, Debugging Options): Add
-gz[=type].
(Debugging Options): Document -gz[=type].
