Keith Packard via Newlib 2eafcc78df libm/math: Make yx functions set errno=ERANGE for x=0 
The y0, y1 and yn functions need separate conditions when x is zero as
that returns ERANGE instead of EDOM.

Also stop adjusting the return value from the __ieee754_y* functions
as that is already correct and we were just breaking it.

Jozef Lawrynowicz d451d9ec78 Use HUGE_VALF instead of HUGE_VAL in single-precision float libm math functions 
This patch replaces instances of "(float).*HUGE_VAL" with a direct usage of
HUGE_VALF, which is also defined in math.h.

Jozef Lawrynowicz 7db203304e Remove HUGE_VAL definition from libm math functions 
This patch removes the definitions of HUGE_VAL from some of the float math
functions. HUGE_VAL is defined in newlib/libc/include/math.h, so it is not
necessary to have a further definition in the math functions.
