[COMMITTED 2.39 4/4] math: Provide missing math symbols on libc.a (BZ 31781)

[Aurelien Jarno]

From: Adhemerval Zanella <adhemerval.zanella@linaro.org>

The libc.a for alpha, s390, and sparcv9 does not provide
copysignf64x, copysignf128, frexpf64x, frexpf128, modff64x, and
modff128.

Checked with a static build for the affected ABIs.
Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

(cherry picked from commit eaa8113bf0eb599025e3efdbe1bb214ee8dc645a)
