This option enables the KUnit test suite for the polynomial_calc()
function, which evaluates integer polynomials using factor
redistribution to avoid overflow.
The test suite verifies correctness for constant, linear, and
quadratic polynomials, negative coefficients, per-step dividers,
divider_leftover, total_divider scaling, and a real sensor
N-to-temperature conversion polynomial.
If unsure, say N
