python{39,310,311,312,313}: Allow using cc to resolve dynamic libraries

Browse Source 
This patch hasn't been complete since an alternate case was added to
cpython which allows using ld(1) to resolve libraries. In addition to
this, the stated reason for the patch, to improve startup times by
preventing cpython from invoking gcc to resolve libuuid, has not been an
issue since that logic was removed in cpython 3.9. Finally, this patch
creates a disparity between Linux and other operating systems (I am
working on FreeBSD right now) since the ld(1) case is system gated.

Since it no longer accomplishes its stated purpose, is no longer needed,
and creates platform disparities, we should remove it.

I've left the half of this patch which prevents /sbin/ldconfig from
being invoked, since no nix-compiled program should ever be invoking
absolute paths like this.
