Also, why are we parsing xcoff32 headers in there? AIX OpenJDK will always be
64-bit. So, you can replace the whole xcoff32 section with assert( f_magic ==
U802TOCMAGIC, ..). The function becomes a lot simpler then.

But looking at the using code, returning NULL in case there is no contained
libpath would be actually easier, see below.
