Solution

Issue 1: Ignore the warnings

Note 245372.1 TOC overflow Warning Can Safely Be Ignored

Issue 2: Ignore the warnings

BUG 9828407 states:

Most versions of ld will only forward parse the link line. The warnings are due to the method Oracle uses when parsing the link line to ensure the forward parsing resolves the symbols we require. The side-effect of this on some platforms, such as AIX, is that we then end up reporting a lot of duplicate symbols due to the multiple inclusions of the libraries on the link line ... These are just 'noise' from the linker being 'pedantic' on AIX ... but it does no harm and can be safely ignored.
