Disclosure: I'm not a numpy developer

You've certainly got a functional numpy installation if those are the only two tests failing.  Those two tests are related to the distance between floating-point numbers using long double precision (128 bits).  If you're not using long doubles, then you probably don't need to worry about them.  Still, the developers are interested in tests failing on non-x86 corner cases like this so thanks for reporting.
