+Create e5500 specific math_private.h and let it include when compiling for e5500/64bit core
+We prefefine __CPU_HAS_FSQRT to 0 and then in general ppc64 math_private.h we check if its
+already defined before redefining it. This way we can ensure that on e5500 builds it wont
+emit fsqrt intructions
