I agree. Besides, I can't think of any reason why a correct program
would want to add undefined strings to the environment. I was also a
little concerned that function wrapping on ppc64-linux is not as
robust as on the other Linux targets - if the original function
longjmps instead of returning properly then it will get into difficulties.
But that doesn't sound like a problem here. Yes, pls commit.
