Subject: [PATCH] build-system/python: Move the check phase after the install
phase.
A reproducibility problem was discovered while packaging python-pygithub where
the bytecode produced by running the tests would interfere with the result of
the install phase byte compilation. Moving the check phase after the install
phase solves the problem.
* guix/build/python-build-system.scm (%standard-phases): Add comment, move
the check phase after the install phase.
