>Description:
	The arm32 setting of infinity is incorrect, causing HUGE_VAL to be not
	very huge at all :-(

	
>How-To-Repeat:

	Compile and run the following program, it should print "Inf, Inf",
	but doesn't.

	#include <math.h>
	union{int x[2]; double d;} p;

	main()
	{
	  p.x[0] = 0x7ff00000;
	  p.x[1] = 0;
	
	  printf("%f, %f\n", HUGE_VAL, p.d);
	}

	
>Fix:

	Correct setting (in lib/libc/arch/arm32/gen/infinity.c) should be

	const char __infinity[] = { 0, 0, (char)0xf0, 0x7f, 0, 0, 0, 0 };
