this affects 2.7 as well. the problem was introduced by r78136 which skips out of the directory containing newly built libpython2.7, so the linking command cannot find it in -L. and fails (unless a systemwide libpython is already present)

the tests should probably specify that they want to link to a specific file, instead of relying on -lpython
however, i have no idea how to do that in general, let alone within distutils :/
