    build: improve SIGPIPE emulation on mingw
    
    On mingw, even doing 'm4 --help | sed 1q' would result in
    warnings about EINVAL, because mingw has odd pipe behavior
    and doesn't fail with EPIPE when no one is reading the
    other end.  Gnulib works around most of this.
    
    Meanwhile, strtol was marked obsolete in gnulib.
    
    * gnulib: Update to latest.
    * m4/gnulib-cache.m4: Import sigpipe module, drop strtol.
