test_sysconfig fails when executed from within a venv #104097
Description
Bug report
As part of adding property-based tests to the standard library's test suite (#22863), I discovered that test_sysconfig apparently will fail when the test suite is executed from a virtual environment. To reproduce:
./python -m venv venv
venv/bin/python -m test -W test_sysconfig
The result:
