RFR: JDK-8071651: infinite build loops in 9-dev windows platform on Jan 26

Wed Jan 28 10:46:07 UTC 2015

Hello,

Please review this followup fix for the vardeps patch (JDK-8069261). It 
seems that in Cygwin, when running gnu make 3.82, whitespace isn't 
stripped in the exact same way as on other versions of gnumake that I 
have tested (4.0 on all platforms, 3.81 on linux). The fix to this 
problem was to change the string equals macro that I created and strip 
the arguments in that.

Added a test that reproduces the problem.
