this is very good.  Are you able to run and debug the examples on the GDB SIS?

I think the application build system is highly user specific.  Most users will 
choose the build system with that they are familiar.  RTEMS provides support 
for a very simple Makefile system used in the examples:

http://git.rtems.org/examples-v2/
http://git.rtems.org/network-demos/

This system is also used by the Eclipse plug-in to deduce the BSP settings for 
the compiler, linker, etc.

http://wiki.rtems.org/wiki/index.php/RTEMS_Eclipse_Plug-in

It is a CDT extension (the C/C++ Development Toolkit for Eclipse).  You can 
create RTEMS applications with it and don't have to worry about the build 
systems since Eclipse will do this for you.

For larger projects I recommend to have a look at WAF.
