elfcompress: New utility.

Usage: elfcompress [OPTION...] FILE...
Compress or decompress sections in an ELF file.

 -f, --force              Force compression of section even if it would
                          become larger
 -n, --name=SECTION       SECTION name to (de)compress, SECTION is an
                          extended wildcard pattern (defaults to
                          '.?(z)debug*')
 -o, --output=FILE        Place (de)compressed output into FILE
 -p, --permissive         Relax a few rules to handle slightly broken ELF
                          files
 -q, --quiet              Be silent when a section cannot be compressed
 -t, --type=TYPE          What type of compression to apply. TYPE can be
                          'none' (decompress), 'zlib' (ELF ZLIB compression,
                          the default, 'zlib-gabi' is an alias) or
                          'zlib-gnu' (.zdebug GNU style compression, 'gnu'
                          is an alias)
 -v, --verbose            Print a message for each section being
                          (de)compressed
 -?, --help               Give this help list
     --usage              Give a short usage message
 -V, --version            Print program version
