    autopoint: Fix infinite recursion when tracing configure.ac
    
    Reported by Andreas Henriksson at:
    <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=764580>
    * autopoint.in (func_trace_autoconf): Temporarily redefine
    built-in macros, instead of undefining.
    * gettextize.in: Likewise.
