to emit the function body unless the address is explicitly

we are using a new GCC with the C99-compatible behaviour, or

function body *must* be emitted. Likewise, a function declared
without either 'extern' or 'static' defaults to extern linkage
(C99 6.2.2p5), and the compiler may choose whether to use the
inline version or call the extern linkage version (6.7.4p6).
