makefile: fix eqy failure, use ORFS built eqy

[oharboe]

@maliberty A quick stab at boarding up the broken window with room to refine in the future...

Error: cts.tcl, 102 couldn't execute eqy: no such file or directory

@maliberty failed... Something else is needed here. Thoughts?

You might look at KLAYOUT_CMD and how we have a preferred path and a fall back. Currently there is no version requirement though I suppose that could arise in the future.

Where is eqy locally and on the build server in ORFS?

I think you should use the location that the dependency installer uses or the users path rather than list other possible locations.
