from an RTEMS project point of view it would be better to fix this issue 
in the master branch, since your use case seems to be quite reasonable.

Just copy and paste and modify the rtems_cpu_usage_report() 
implementation. This will work for the moment, however, it will probably 
not work with the next RTEMS version you use and nobody else can benefit 
from it.
