Use libc from agbcc instead of standalone newlib\nYou must have AGBCC commit 80d029caec189587f8b9294b6c8a5a489b8f5f88 in order to compile pmd_red.gbalibc

-/* __ieee754_hypot(x,y)
- *
- * Method :                  
- *	If (assume round-to-nearest) z=x*x+y*y 
- *	has error less than sqrt(2)/2 ulp, than 
- *	sqrt(z) has error less than 1 ulp (exercise).
- *
- *	So, compute sqrt(x*x+y*y) with some care as 
- *	follows to get the error below 1 ulp:
- *
- *	Assume x>y>0;
- *	(if possible, set rounding to round-to-nearest)
- *	1. if x > 2y  use
- *		x1*x1+(y*y+(x2*(x+x1))) for x*x+y*y
- *	where x1 = x with lower 32 bits cleared, x2 = x-x1; else
- *	2. if x <= 2y use
- *		t1*y1+((x-y)*(x-y)+(t1*y2+t2*y))
- *	where t1 = 2x with lower 32 bits cleared, t2 = 2x-t1, 
- *	y1= y with lower 32 bits chopped, y2 = y-y1.
- *		
- *	NOTE: scaling may be necessary if some argument is too 
- *	      large or too tiny
- *
- * Special cases:
- *	hypot(x,y) is INF if x or y is +INF or -INF; else
- *	hypot(x,y) is NAN if x or y is NAN.
- *
- * Accuracy:
- * 	hypot(x,y) returns sqrt(x^2+y^2) with error less 
- * 	than 1 ulps (units in the last place)
