RFR: JDK-8026528: [build] configure does not recognize newer make in cygwin

[Erik Joelsson]

Please review this simple patch extending the recognized make versions 
in configure to 4.0, which was recently released and is already default 
in Cygwin. I also removed the version check in NewMakefile.gmk since it 
seems redundant having already done it in configure. They were also not 
in sync.

I have successfully built on Windows with make 4.0 and it seems to work 
fine.
