Subject: [PATCH] TST: fix test_validate_transcendentals skip condition to
match SVML dispatch
The test was running on machines with FMA3+AVX2 or AVX512F, but the
SVML code path requires AVX512_SKX (F+BW+DQ+VL). On machines without
AVX512_SKX, the glibc libm scalar fallback is used, which exceeds the
2 ULP tolerance for some float64 cbrt inputs.
