[gentoo-dev] [PATCH distutils-r1 2/2] Export PYTHONPATH=${BUILD_DIR}/lib for out-of-source builds.

[Michał Górny]

This may help a few test suites and shouldn't hurt much of the others
(which weren't broken already).

Done only for out-of-source builds as that's where we control the build
directories.
