Hi! This testcase expects to find DWARF extensions, but those are disabled by default on darwin/vxworks because broken tools there don't handle debug info very well.
I think the following patch (regtested on x86_64-linux and i686-linux) should fix it, but I have no access to darwin, so can't verify.
