COMPRESS_DEBUG_ZLIB isn't needed. This patch removes COMPRESS_DEBUG_ZLIB
and replace COMPRESS_DEBUG_ZLIB with COMPRESS_DEBUG_GNU_ZLIB.
bfd/
* bfd-in.h (compressed_debug_section_type): Remove
COMPRESS_DEBUG_ZLIB.
* bfd-in2.h : Regenerated.
gas/
* as.c (parse_args): Replace COMPRESS_DEBUG_ZLIB with
COMPRESS_DEBUG_GNU_ZLIB.
* config/tc-i386.c (flag_compress_debug): Likewise.
ld/
* emultempl/elf32.em (gld${EMULATION_NAME}_handle_option):
Replace COMPRESS_DEBUG_ZLIB with COMPRESS_DEBUG_GNU_ZLIB.
