rpath argument change in GCC / LD

[Michael Dickens]

So from your list below as I've labeled them, only (3) works in my testing with GCC8 as the pass-through compiler between the SciPy script creating this code & the linker. I have not tested any other GCC version, but I'm guessing it's the linker that's called that determines whether the -rpath flag usage is valid. As I said: This is a fairly recent change in the linker, which I'm guessing has something to do with which linker is being used: MP's or Xcode's. All of my testing over the weekend was on 10.14, which passes the link command through to Xcode's linker. I will try testing on my older OSX boxes to see what happens there, since I'm guessing they use MP's linker (as Xcode's is so old). If (3) works on all of the linkers, then I'll go with it (patching to include the ""s). - MLD
