Any idea why the xray tests need to manually specify the standard library like this instead of letting the compiler driver do it automatically?

It uses the C compiler invocation for the linking, perhaps to avoid picking up the default C++ run-time libraries.

That's a good question @tstellar -- a lot of this is cargo-cult copy-pasted from other sanitizer tests. The reason I think is because there are sanitized builds of the standard library (libc++ at least) and this allows us to pick those as well (say if we're building an address-sanitized XRay implementation).
