[Bug libc/6411] PowerPC: Extend fpu fenv operations to operate on 64-bit FPSCR

That's a non-standard header, there is no documentation.  But it's an exported
header.  Nobody is supposed to use the values of this type without the
functions/macros in this header.  So there is no problem with using a different
representation.

That is the intend of my comment.
