powerpc: Fix fsqrt build in libm [BZ#16576]
Some powerpc64 processors (e5500 core for instance) does not provide the fsqrt instruction, however current check to use in math_private.h is __WORDSIZE and _ARCH_PWR4 (ISA 2.02). This is patch change it to use the compiler flag _ARCH_PPCSQ (which is the same condition GCC uses to decide whether to generate fsqrt instruction). It fixes BZ#16576.
