Don't provide scalb/significand _FloatN aliases [BZ #31760]
scalb is a deprecated interface which was obsolescent in POSIX.1-2001,
removed in POSIX.1-2008, never made to C standard. significant was
originally from BSD and never made in any standard. Fix BZ #31760 by
not providing _FloatN aliases for them.
