util: limit gnu_printf format attribute to gcc >= 4.4.0

Browse source 
The gnu_printf format attribute was introduced in gcc 4.4.0
https://gcc.gnu.org/legacy-ml/gcc-help/2012-02/msg00225.html.

Use the printf format attribute on earlier versions of gcc and clang
(which claims to be gcc 4.2.1 in builtin defines) to fix the build with
gcc 4.2.1.
