This test was failing when run against a "remote" target (at least
android, but possibly others). I've skipped it because it's not really
applicable to the remote test suite, but I did notice something you
may want to know about while investigating:
The test verifies that the target triple is deduced as "x86_64--",
which is true when we run it with the "host" as the currently selected
platform. However, if the currently selected platform is
"remote-android", then something interesting happens: The platform of
the newly created target is set to "host" (which I presume is correct,
as that's the platform which is selected in the non-remote case as
well), however, the *triple* is deduced as "x86_64-apple-macosx"
(which seems a bit odd).
I don't really know what this means, but I'm writing it here in case
that's something you want to know about.
