maybe this can be useful:

        The special exit code 125 should be used when the current source 
code cannot be tested. If the

        script exits with this code, the current revision will be 
skipped (see git bisect skip above)

this will build only the external module without any prerequisites in 
other modules; try instead "make liborcus.all" - this will read all 
makefile but build only what's necessary for the one module.
