[tor-commits] [tor/master] Add --enable-zstd to our configure script.



commit ce1feae9d9a4366e3cd93a68416841d0c6a636c5
Author: Alexander Færøy <ahf@xxxxxxxxxxxxxx>
Date:   Tue Apr 18 17:54:59 2017 +0200

    Add --enable-zstd to our configure script.
    
    This patch adds support for enabling support for Zstandard to our configure
    script. By default, the --enable-zstd option is set to "auto" which means if
    libzstd is available we'll build Tor with Zstandard support.
    
    See: https://bugs.torproject.org/21662
