    autoconf: Allow non-pkg-config builds to succeed
    
    The variable no_x was being set to yes when libX11 was not found through
    pkg-config. This causes AC_PATH_XTRA to skip its search for the X11
    libraries, which was not the intended effect. Also switched to using the
    PKG_CHECK_EXISTS autoconf macro.
