[COMMITTED] math/test-fenvinline: avoid compiler warning

[Chris Metcalf <cmetcalf at ezchip dot com>]

On tile (and any other machine with no FP exceptions) the
feenable_test() function will generate a "function defined but
not used" warning because all of the callers are commented out.
We already were ifdef'ing out the body of the function, so instead
just ifdef out the entire function if FE_ALL_EXCEPT == 0.
