My previous approach cannot be completed because of the presence of optional arguments. And even having some valid call, we cannot construct valid decl from this (or we will need some additional logic, which will "complete" such decls).
The idea itself is pretty simple: why don't turn external functions/intrinsics into varargs function (in C/C++ sense). In this case trees won't became bogus anymore, however, having call to varargs function can (in theory) disable some optimization performed on it. Attached patch works fine for me.
