fix configure (by running autoconf on FC6 and applying our local mods). Configure does now not use anymore XtMalloc and libXt to test if the X11 libs are installed. XtMalloc is part of libXt and not libX11. In the past this was not a problem as libXt was part of x11-devel or xorg-devel, but now FC6, Ubuntu, Debian, etc. have made a separate libXt-devel or equivalent package. Now a proper libX11 function is used for testing libX11 availability. This should solve a number of problems where libAfterImage was built without X11 support.
