Don't attempt to compress bss sections
It doesn't make sense to try to compress a section without contents since those sections take no space on disk. Compression can only increase the disk image size. * coffgen.c (make_a_section_from_file): Exclude !SEC_HAS_CONTENTS sections from compression and decompression. * elf.c (_bfd_elf_make_section_from_shdr): Likewise.
