commit 4c401016623a0befb9d048c9ad7e3fb6d9e8df54
Author: Martin Roth <martinroth at google.com>

    buildgcc: support pigz and lbzip2 decpmpressors if installed.
    
    These are multi-threaded decompressors for .gz and .bz2 compressed
    files.  If they're installed, use them to decompress, if they're not,
    use the standard single-threaded decompressors.
