/bin/check_reqs is broken

Running `/bin/check_reqs` gives the following error:

Environment is not supported: TypeError: Cannot read property 'os' of undefined

This happens when `getMinimalRequiredVersionFor` is called without `windowsTargetVersion, windowsPhoneTargetVersion` params. (run -> checkOS (without these two params) -> getMinimalRequiredVersionFor (also no params of course))

As I understand it this might be the case since 2 years, when these params were added to quite some methods calls - and to be read from config.xml first:

Unfortunately the pure `run` call wasn't updated - and as it doesn't know anything about the target versions, it can not work.
