No, it's not.

In tree you'll find scripts/checkkconfigsymbols.py. That catches over
90% of the stuff my local script catches, in less than 10% of runtime.
It would certainly have caught your use of USB_ARCH_HAS_EHCI.

My local script is my third (or fourth) attempt at a script that checks
these kind of issues. I've used it on linux-next since for about 3/4 of
a year now. While doing that I ran into people that are planning into
adding similar, but far more advanced, functionality into one of the
bots that is checking linux. So I never bothered making my script
public. (I'm not sure what the status of those plan is now.)

In the mean time I'll keep on checking linux-next with my script. That
should also help to see what problems an actual bot could run into, for
the benefit of those people. Problems like:
- should it check each commit (I think it should only check releases);
- should it be a true bot (I think it needs a wetware frontend to
  filter out non-issues).

Hope this answers your question.
