Note this has nothing to do if the symbol is used in modules or not.
It's just that EXPORT_SYMBOL (which publishes the symbol to the module
linker). I havn't checked, but I assume the compiler interprets

EXPORT_SYMBOL(rational_best_approximation);

just as declaration of a function EXPORT_SYMBOL and doesn't generate the
needed magic to actually export rational_best_approximation.

Best regards
Uwe
