mainboard: -ffreestanding so 'main' is not necessarily entry

From the C specification in 5.1.2.1 Freestanding environment;

"In a freestanding environment (in which C program execution may take
    place without any benefit of an operating system), the name and type of
    the function called at program startup are implementation-defined."

Clang complains about these being missing as Clang is somewhat more
    strict about the spec than GNU/GCC is. An advantage here is that a
    different entry-point type-signature shall now be warned about at
    compile time.
