make test WAY=xxx broken

It seems like running

make test WAY=someWay

is broken. Looking at the runtest.py, it seems that we parse the arguments to the test driver before reading the configuration file (e.g. config/ghc), and thus the --way flags arguments are not available.

E.g. the way options get populated, once the --config-file argument is processed. But the argument parser seems to be eager and as such the handling of the --config-file happens *after* all of the arguments have been parsed. Therefore the set of available --ways are always the empty set.

I don't know if python2 was lazy here. But with python3 using --way seems impossible.
