Are these new tests limited to x86 or some long double > assumptions? These tests require the availability of a 10- or 16-byte-wide REAL type, respectively. I have to admit that I do not have a complete overview of which targets in GCC's wide portfolio provide such a type. It seems that REAL(16) is supported via libquadmath on 32-bit x86, x86-64 and Itanium at least. I'm not sure about REAL(10). Targets that do not support such a type probably need to be XFAILed.
