* elfcode.h (bfd_section_from_shdr): If section is SHT_PROGBITS, and the name starts with .debug, .line or .stab, set SEC_DEBUGGING. * elf32-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added SEC_DEBUGGING to section_flags. * elf64-target.h (TARGET_BIG_SYM, TARGET_LITTLE_SYM): Added SEC_DEBUGGING and SEC_CODE to section_flags. * bfd-in2.h: Updated.
