I don't quite understand.  Are you allocating an actual PLABEL
(2 memory words) inside this function?  What are you allocating
it from?   Where does it get freed if the library is unloaded?

This is a very poor choice in name since it doesn't really give
much idea what it does.  I'd recommend something like
"_rtld_plabel_function" instead.
