commit 0088fa73d033b89b41265da5bdf4c1556eb1a61a
Author: David Cantrell <dcantrell@redhat.com>

    Handle initGenericErrorDefaultFunc -> xmlSetGenericErrorFunc
    
    Newer releases of libxml have deprecated initGenericErrorDefaultFunc
    in favor of xmlSetGenericErrorFunc, so make sure we handle building on
    those systems.
