To test PR 4172 on linux one needs a chroot. The following test is run on
archlinux using systemd-nspawn (a chroot on steroids, see
https://wiki.archlinux.org/index.php/Systemd-nspawn).
1) Setup systemd-nspawn by installing arch-install-scripts and by using
pacstrap to install the archlinux 'base' package group in the /tmp/chroot
container, this installs about 600M of archlinux packages in the chroot:
$ mkdir /tmp/chroot
$ pacman -S arch-install-scripts
# pacstrap -i -c -d /tmp/chroot base --ignore linux
2) Build and install Python in the /tmp/python-build DESTDIR directory:
$ mkdir /tmp/python-build
$ ./configure --prefix=/ --without-ensurepip && make
$ make DESTDIR=/tmp/python-build install
3) Copy the Python distribution to the chroot directory (note the trailing
slash in the source directory):
# rsync -av --keep-dirlinks /tmp/python-build/ /tmp/chroot
4) Boot into the chroot container and run python:
# systemd-nspawn -b -D /tmp/chroot
