PEP 571: Update permitted GCC_4.5.0 (#1180) 

Matching the symbols permitted for x86_64 by GCC_4.3.0 require a limit of GCC_4.5.0 on i686 CentOS 6.

This does create the risk that 32-bit extension modules using `__extendxftf2` may not actually be portable to all 2010 era systems, but most of those other than RHEL/CentOS 6 have already hit the end of their respective support periods.

Summary of changes to \PEP 571
==============================
The following changes were made to this PEP based on feedback received after
it was approved:
* The maximum version symbol of ``libgcc_s`` was updated from ``GCC_4.3.0``
to ``GCC_4.5.0`` to address 32-bit Cent OS 6. This doesn't affect x86_64
because ``libgcc_s`` for x86_64 has no additional symbol from
``GCC_4.3.0`` to ``GCC_4.5.0``.
