tests/run-make/non-pie-thread-local/rmake.rs

// It was once required to use a position-independent executable (PIE)
// in order to use the thread_local! macro, or some symbols would contain
// a NULL address. This was fixed, and this test checks a non-PIE, then a PIE
// build to see if this bug makes a resurgence.
