I'm a bit afraid to be so specific here. Currently we should get to this
branch only if there is no compat syscall defined (as far as I can tell)
but that may change.
I would settle for more vague "Syscall %s() not implemented". The fact
that it's the compat version should be known from the test name.
Or alternatively we can add callback parameter to the ALL CAPS functions
and make sure that the particular error is printed only when compat
syscall is called.

Generally this version looks fine to me.
