[AVR] Use the correct address space for non-prototyped function calls

Some function declarations like this:

    void foo();

do not have a type declaration, for that you'd use:

    void foo(void);

Clang internally bitcasts the variadic function declaration to a
function pointer, but doesn't use the correct address space on AVR. This
commit fixes that.

This fix is necessary to let Clang compile compiler-rt for AVR.
