After JDK-8210863, the build would start to fail with cryptic:

Compiling gtk_interface.c (for libawt_xawt.so)
/home/buildbot/worker/jdkX-linux/build/src/java.desktop/unix/native/libawt_xawt/awt/awt_GraphicsEnv.c:37:35: fatal error: X11/extensions/Xrandr.h: No such file or directory
 #include <X11/extensions/Xrandr.h>
                                   ^
compilation terminated.

Installing libxrandr-dev helps to resolve it, but autoconf should really check on it, and fail with sane message during the configure.
