[PATCHv2 10/14] Add note about nexttoward test cases in libm-test.inc

[Paul E. Murphy]

The second argument always takes a long double.  Leave
a note here in case someone attempts a global update
similar to the previous commit.

	* math/libm-test.inc (nexttoward_test_data):
	Add comment about long double second argument.
