math: Remove __XXX math functions from installed math.h [BZ #32418]
Since libm doesn't export __XXX math functions, don't declare them in the installed math.h by adding <bits/mathcalls-macros.h> to declare __XXX math functions internally for glibc build. This fixes BZ #32418. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Sam James <sam@gentoo.org>
