Contrary to what I had thought: this is indeed caused by spurious
overflows from libgcc (confirmed with the patch applied to libgcc).
We can suppress the all errors with XFAIL_ROUNDING_IBM128_LIBGCC.

---8<---

Ignore 112 errors in math/test-ldouble-fma and math/test-ildouble-fma
when IBM 128-bit long double used.
These errors are caused by spurious overflows from libgcc.

	* math/libm-test-fma.inc: Set XFAIL_ROUNDING_IBM128_LIBGCC to
	more tests.
