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. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
