RFR: 7190512 Fix for 7181175 broke hotspot/make/windows/create.bat builds.

[Tim Bell]

Hello all-

After the fixes for 7181175 hit the hotspot-rt forest, users noticed 
that hotspot/make/windows/create.bat builds were broken.

This is a supplemental fix that restores building using that .bat file.  
Note that this is not on the 'product' build path at all - this is 
something HotSpot developers use to get a fast build of their VM changes.

Dan - as gatekeeper-of-the-month, would you be able to take this?

Thanks-

Tim
