Commit Message

Adhemerval Zanella Netto March 21, 2024, 4:43 p.m. UTC 
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.
I also checked that a stack build using fmod/fmodf correctly
resolves on both ABIs.
