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.
