trunc, truncf on Solaris

[Bruno Haible]

On Solaris 8, I'm seeing these errors:

  ../gllib/math.h:816: error: 'truncf' was not declared in this scope
  ../gllib/math.h:835: error: 'trunc' was not declared in this scope

This fixes it, by using the simpler idiom for a missing function.

        math: Fix some C++ test errors on Solaris 8.
        * lib/math.in.h (truncf, trunc): Use simpler idiom.
