[PATCH v3 2/7] math: Fix i386 and m68k fmod/fmodf on static build (BZ 31488)

Message-Id: <20240402140644.2172819-3-adhemerval.zanella@linaro.org>

The commit 16439f419b removed the static fmod/fmodf on i386 and m68k
with and empty w_fmod.c (required for the ABIs that uses the newly
implementation).  This patch fixes by adding the required symbols on
the arch-specific w_fmod{f}_compat.c implementation.

To statically build fmod fails on some ABI (alpha, s390, sparc) because
it does not export the ldexpf128, this is also fixed by this patch.

Checked on i686-linux-gnu and with a build for m68k-linux-gnu with
'make test t=math/test-{float,double}-modf-static build-math-static-tests=yes'.
