At least for sysv4 you probably also need to be checking flag_pic,
since a non-static function in a shared library can still be
overridden.  I don't know if the semantics of AIX shared libraries
differ.

Unless of course the linker is smart enough to make sure that the
short branch makes it to a PLT stub...
