commit dd484d6b09be5c2ba25592c0e592d0e03233368c
Author: Martin Roth 
Date:   Sun Mar 20 12:38:48 2016 -0600

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.
