Some recent math optimizations remove some symbols from the static build
and due to the limited static build check, along with a --disable-shared
being broken for some time [1]; this issue has slipped some releases.

Although the fix is straightforward, I added an extra framework to
enable static build for select math libraries using the generic type
framework (which autogenerated the tests for all supported types using
the C template files). This should help with future static build tests.

Although the second and fifth patches should be back portable, I also
added some patches to removed the i686 assembly optimizations.

Adhemerval Zanella (6):
  math: Add support for auto static math tests
  math: Fix i386 and m68k fmod/fmodf on static build (BZ 31488)
  i386: Use generic fmod
  i386: Use generic fmodf
  math: Fix i386 and m68k exp10 on static build
  i386: Use generic exp10
