it's quite confusing. It seems that the `executable=`
is not documented.
I already have had trouble while setting the executive name for
sage.features.ecm - it had to be done via a global variable.
Now it's another case like this, and it's really ugly to do the same. I'd
rather have an option to encapsulate/cache the absolute name in the
corresponding class, and do not search for exacutables in fixed directories all
the time.
