make: *** [Makefile:19: exectime] Fel 1

Today it's only possible to define numer of execution iterations. Normally, if one talks about statistics, the target is to gather data until the relative standard error is below a certain level, say 5%. It would've been nice to define this instead of iteration count.

Side note: if iteration count is given, this should probably be used as maximum (or minimum) iterations before giving up.
