Problem building RTEMS 4.11 from a clean pull from git using rsb. _libatomic.h is missing.

[Sebastian Huber]

I guess you try to build the Git master (RTEMS 4.12) with the 4.11 tool 
chain. This doesn't work. You have to checkout the RTEMS 4.11 branch if 
you want to use the 4.11 tool chain. However, I would use the 4.12 tool 
chain and the Git master.
