Using the "exlude-libs ALL" linker option to prevent symbol preemptions

to the openssl symbols imported by our redistributed python libs.

The python module prefered system headers and libraries over the ones
requested by AOO's configure scripts. This impacted the build for packages
intended for redistribution, especially for the OpenSSL provided libs.
