--with-devkit doesn't control nmake

For your build to pick up nmake from some other VS installation means 
you must have that VS installation in your path. Normally, only the 
devkit bin dirs will be in the path if you start with a clean 
environment. We have simply not encountered that before, but it is 
definitely a bug. However, the hotspot build-infra project is currently 
rewriting the hotspot makefiles (see build-infra/jdk9 forest if you are 
interested) and we are getting rid of nmake. This project will go into 
JDK 9 in hopefully not too long a time.

Unless this is causing actual trouble now, we in the build group will be 
reluctant to spend time on fixing the issue. We would of course welcome 
contributions from others if someone is willing to do the work.
