This patch tweaks a few tests that currently rely on .pyc files being written, causing them to fail (or crash) when running 'make test TESTPYTHONOPTS=-B'. All these are purely test failures, not failures in the tested code (unlike issue #11417, which is a failure in bdist_rpm instead of the test.)

(This patch is for 3.1; the patch for 3.2/default is slightly different. I also have the same patch for Python 2.6/2.7, but I'm not sure if it's worth applying.)

As per issue #11417, updated to also skip the tests in distutils/tests/test_bdist_rpm.py when not writing bytecode.

Attached an updated patch against 3.2.

+skip_if_dont_write_bytecode = unittest.skipIf(
+        sys.dont_write_bytecode,
+        "test meaningful only when writing bytecode")

Maybe this could be added to the test.support module?

There are a couple more tests elsewhere that use @skipIf(sys.dont_write_bytecode, ...) directly, but I don't think it's generic enough to be moved to test.support.

Looks fine.

Can this go into 2.7 too?
