They have different output directories. In the case of the same output dirs
that will definetly produce problems (though not for 'everybody' as it
seems), we had that with another kdevelop plugin which runs a
parser-generator and there where two targets (one custom-target one normal)
that both depended onto the generated files. This produced build-erros when
running make -j, but not for everybody and not reliably...
