it seems like you want to add an attribute to the function, similar to what we
do with LIBC_INLINE. Is there a reason you can't just put
`LIBC_PRINTF_MODULE_DECL` in front of the function definitions? That seems like
it would be simpler and would avoid putting the body of the function inside the
macro.
