Yaakov Selkowitz 722e363c4d math: guard BSD finite/isinf/isnan functions properly in math.h
Now that we have properly functioning feature test macros, the BSD
floating-point classification functions can go into math.h instead of
the non-standard ieeefp.h, and not under the C99 guard:

http://man7.org/linux/man-pages/man3/finite.3.html

The isnan function was in earlier versions of SUS but removed starting with
POSIX.1-2001, compare:

http://pubs.opengroup.org/onlinepubs/007908799/xsh/math.h.html
http://pubs.opengroup.org/onlinepubs/009695399/basedefs/math.h.html

Note that the isinf and isnan functions (but not the variants) conflict
with functions by the same name in C++11, hence they (and only they)
need to be hidden:

Yaakov Selkowitz ac2f9e23ec 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.
