commit 298529bf8adc38ed602eab300c63bbc68510e5a3
Author: Herbert Valerio Riedel <hvr at gnu.org>
Date:   Mon Dec 14 07:58:30 2015 +0100

    Remove obsolete `--with-cc` flag from configure.ac
    
    This non-standard flag was used previously by GHC's build-system to set the `CC` variable.
    
    See https://phabricator.haskell.org/D1608 for more details
