Ok, I seem to remember a discussion about this some time ago. Options with

default: null

cannot be changed by the user. I think for the RTEMS version the reason 
was that users should be forced to use the right tool chain.

We could change the RTEMS version options to

default: 6

for example.

At the moment you have to patch spec/build/cpukit/optvermaj.yml to build 
with a tool chain of the wrong version.
