The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default. Since BSF_KEEP_G is never used, it is renamed to BSF_ELF_COMMON for ELF common symbols. bfd/ PR ld/19645 * bfd.c (bfd): Change flags to 20 bits. (BFD_CONVERT_ELF_COMMON): New.
