    [libstdc++] [testsuite] require cmath for [PR114359]

    When !_GLIBCXX_USE_C99_MATH_TR1, binomial_distribution doesn't use the
    optimized algorithm that was fixed in response to PR114359.  Without
    that optimized algorithm, operator() ends up looping very very long
    for the test, to the point that it would time out by several orders of
    magnitude, without even exercising the optimized algorithm that we're
    testing for regressions.  Arrange for the test to be skipped if that
    bit won't be exercised.
