    Always use -Xlinker for -rpath
    
    Currently we use `-Wl` which takes a list of
    comma-separated options. Unfortunately that
    breaks when you use it with `-rpath` and
    a path that has commas in them.
    Buck, the build system, produces paths with
    commas in them.
    
    `-Xlinker` doesn't have this disadvantage
    and as far as I can tell is supported by
    both `gcc` and `clang`. Anecdotally `nvcc`
    supports `-Xlinker`, but not `-Wl`.
    
    Test Plan: ./validate, harbourmaster
