Change the test source location to support evolving downstream testing
requirements. This is needed both for downstream certification
activities and changes to test development for internal infrastructure
differences.
The code in CPython uses XML_SetReparseDeferralEnabled when expat is >= 2.6 during the build.
However, when users upgrade Python independently on the expat package,
they may have expat 2.5 installed and see errors like:
$ python3.1X -m venv venv
Error: Command '['venv/bin/python3.1X', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
$ venv/bin/python3.1X -m ensurepip --upgrade --default-pip
