Because we'd end up in an arms race of benchmark argv[0] name and
what is hard-coded in Open MPI. Users/customers/partners would soon
enough figure out that this is what we're doing and either use "mv"
or "ln -s" to get around our hack and see the real numbers anyway.

In short: it's an even dirtier trick than header caching (for
example), and we'd get beat up about it.
