Re: [PATCH v1 1/2] PR116080: Fix tail call dejagnu checks

[Andi Kleen]

I'm going to revert the patch for now. There are two problems:

- The new tests don't have a unique name so the caching confuses 
the results.
- To test with -O2 we need explicit musttail checks because tail call doesn't
run with -O0 w/o musttail.
