+Add additional check on GST_GL_HAVE_PLATFORM_GLX before using gst_gl_display_x11_new_with_display
+
+This ensures that there is a compile time check for glx support in gstreamer as
+runtime check is not enough because gst_gl_display_x11_new_with_display() API comes from
+gst/gl/x11/gstgldisplay_x11.h which is only included when GST_GL_HAVE_PLATFORM_GLX is defined
+therefore make this check consistent to fix build with some platforms which use pvr gl drivers
+where this problem appear at compile time.

+This issue is 2.40 specific since GLX support is removed [1] from trunk upstream, therefore
+this patch wont be needed when upgrading to 2.42+
