powerpc: Use sqrt{f} builtin
The powerpc sqrt implementation is also simplified:
- the static constants are open coded within the implementation.
- for !USE_SQRT_BUILTIN the function is implemented directly on
__ieee754_sqrt (it avoid an superflous extra jump).
Checked on powerpc-linux-gnu and powerpc64le-linux-gnu.
