Log Message:
tests/lib/libm/t_next: Disable a test if long double is double.
This test, to verify nexttoward(x, x*(1 - LDBL_EPSILON/2)) moves in
the direction of x*(1 - LDBL_EPSILON/2), only makes sense if long
double has more precision than double -- the point of the exercise is
to verify that nexttoward moves even if the direction parameter can't
be rounded to double. But if long double is just double, this test
makes no sense.
