I do not know how much of the graphics toolkit you actually need. One of our long term goals is to build various third party libraries with the RTEMS Source Builder. There is initial support for NTP but the other libraries from the graphics toolkit and add-on packages need to be merged.

Just wanting to reiterate the long term vision.
