reader: Avoid empty return type node for a function type IR 

Sometimes, the function type IR can have an empty node as return type,
to represent void.  This can wreak havoc on some part of the code that
don't expect that.  This patch uses a proper void type node for that
instead.

	* src/abg-reader.cc (build_function_type): If the return type node
	is empty, use a void type node.
