Remove broken ieeefp.h macros
Any attempt to use isnanf, isinff, or finitef from <ieeefp.h> with
GCC 5 on platforms other than SPU result in a "lvalue required as
unary '&' operand" error.
newlib/libc/
* include/ieeefp.h (__ieeefp_isnanf): Remove broken macro.
(__ieeefp_isinff, __ieeefp_finitef): Ditto.
