Fix pixman build with older GCC releases

The following patch fixes building pixman with older GCC releases
such as GCC 3.3 and older (OpenBSD; some older archs use GCC 3.3.6)
by changing the method of detecting the presence of __builtin_clz
to utilizing an autoconf check to determine its presence. Compilers
that pretend to be GCC, implement __builtin_clz and are already
utilizing the intrinsic include LLVM/Clang, Open64, EKOPath and
PCC.
