It would work and would be BSP independent. But it moves the path knowledge
to the command line.

Could it be done with just "/home/hf/development/rtems/b-leon2" and the
user configuration file use @TARGET@/c/@BSP@/cpukit?

Then the option could be --rtems-builddir or something similar.

I am also thinking that as we move to waf, this might be easier to adapt without
changes.

It is possible but it wouldn't be something done on a regular basis.
