three are still failing with 3.4:

cc-4.9.real: error: /tmp/tmpdjxmlia5/xx.cpython-34m.so: No such file or directory

test test_distutils failed -- multiple errors occurred; run in verbose mode for details
1 test failed:

test_build_ext (distutils.tests.test_build_ext.BuildExtTestCase)
test_get_outputs (distutils.tests.test_build_ext.BuildExtTestCase)
test_record_extensions (distutils.tests.test_install.InstallTestCase)

The reason here is that the xx module is not found (where should it be installed in the installed testsuite?).
