Description
Many of the functional Swing tests are failing in Solaris when GTK look and feel is used.  Few regression tests also failed for the same reason. 

Also could be reproduced using SwingSet2

To Reproduce:

1. Run SwingSet2 using the PIT build (7 b94)
2. Switch to the GTK look and Feel
3. Notice the following messages on the console / terminal

dtftest@sfsparc001:...laris_sparc/demo/jfc/SwingSet2$ ../../../bin/java -jar SwingSet2.jar

EVALUATION Also, the gtk_file_chooser_set_do_overwrite_confirmation() is available since GTK 2.8 only.

EVALUATION The fix for 6913179 introduced support for native GTK FileDialog. However, it also requires some functions from the libgthreads library that actually exist in newer versions of GTK only. For instance, the g_thread_get_initialized symbol is requested while it's only available since gtk 2.20. Since this function gets invoked when the GTK is initialized by JDK, the initialization fails, and any Swing application requesting the GTK L&F fails. Probably we should create a boolean flag indicating whether the GTK has already been initialized, rather than relying on a function that is only available in latest GTK versions.

EVALUATION seems to be a regression of 6913179
