-z is "the length of string is zero", can you elaborate on the logic of this check?

I expected this to check for sandbox-profiles-ios argument that's passed when building the profiles.

Yes, this checks that the env variable exists (does not have zero length) before using it. If the env variable does not exist, the ln command will fail.

I think the above test will cover more cases, in case this should happen under other circumstances. Also, it will continue to work if we should rename the argument.

Thanks for reviewing!

My concern is that we will get a way more confusing error from make if this happens under other circumstances. 

So I'd prefer it to be as focused as possible, so that the check is only true when we know it should be true - not when it happens to be true.

That makes sense, I will update the patch.
