@jhuber6 , I had your implementation in mind when I wrote this, The printf wont
be expanded by clang with "-fno-builtin" and users would still have an option
to use a lib variant if need be. This also makes this more elegant as we would
not have to hack the "fno-builtin" handling into the implementation, this is
part of clang builtin handling.
