I came across the subtly when setting up lit for z/OS and running it on a Linux on Power machine. Linux on Power is little endian. This was resulting in all of these tests being run even though the target triple was z/OS which is big endian. The lit should really be checking if the target is little endian not the host. The previous way didn't handle cross compilation while running lit.
