Granted but Laurent Guerby's instructions are on the RTEMS Wiki.

I haven't tried it in a while so I will have to trust you on this one.  
I spoke with
someone who has a working compiler on arm-linux but I have no idea what
version or what patches.

And don't forget....

3.  The last time I checked Ada hello world was about 400K code.  The
Ada run-time is large.   So you need to look at larger targets.  I would 
disconnecting the ARM and Ada requirements if this is a learning project.
Use Ada natively on Linux and work through the on-line tutorials.  Use RTEMS
on an ARM simulator with an existing BSP.
