The gcc manual says:
"You may not use this mechanism to jump to code in a different function.
If you do that, totally unpredictable things happen. The best way to
avoid this is to store the label address only in automatic variables and
never pass it as an argument."
So the configure test is completely broken (pointed out by Eric Botcatzu)
