All right, fine, let's do the environment var. ocperf.py would be
confused if it replaces "perf" to itself. But, you need to do more work:

 1) Sign the OCA;
     http://openjdk.java.net/contribute/

 2) Fix long options handling in pmu-tools:
     https://github.com/andikleen/pmu-tools/issues/62

 3) Pick up the patch from here:
     https://bugs.openjdk.java.net/browse/CODETOOLS-7901842

 4) Fix perfasm to resolve the symbolic event names back from numeric
ones translated by ocperf (is that even possible?);

 5) Test perf, perfnorm, perfasm with custom event types.

 6) Submit for further review.
