TypeError in Travis in less-1.7.0.min.js

Reported by @busykai, so I updated PR #6697 and it passes Travis, but is showing a TypeError:

@WebsiteDeveloper Any ideas about this less-1.7.0.min.js issue? FYI, I reverted to less-1.4.2.min.js in PR #6697 and the problem went away.

[WebsiteDeveloper]

It seems to be a general problem with calls to the Function.prototype.bind function.
Which seems weird as i can't reproduce the failure in vanilla node, but if i put this code

function test (a) {
    return a;
}

var v = test.bind({}, "Test");

at the top of the less file you will get an error there.
I also tried printing out the .bind method, but it seems that somehow the function is undefined in the less file.
As to less-1.4.2 it doesn't use the bind function this is why it seems to work.

I tried to add the Polyfill from the MDN which worked. But we should probably investigate as to why bind is actually not defined there, when it is in a vanilla node environment.

I tracked it back to this issue https://groups.google.com/forum/#!msg/phantomjs/r0hPOmnCUpc/uxusqsl2LNoJ i put up a pull with a polyfill for the bind function. The need for this will probably go away once we upgrade to phantomjs 2 (once it gets released).

Confirmed. Closing.
