The main funcion is needed as we create an executable, its references to
foo are needed, else LTO will remove foo altogether.

Without #include <stdio.h>, some compilers reject it. Also, the string
should be "%d %f" (or replace '+' with ',' in the arguments).
I think it still fails for emscripten (little endian detected as unknown),
but that shouldn't block the patch, which helps for gcc/clang LTO, and
emscripten probably has several other issues anyway.
