[Bug target/16000] for h8 targets variadic functions are not working properly

I think the statments made in the above link regarding variadic functions
are plainly wrong. It may work for sometimes for some targets but definately
not for all targets. The reason is the compiler may and can pass arguments
differently depending on the prototype and especially for varadic functions.

Both the declaration and definition should agree mixing them isn't going to
work.
