    I didn't clarify properly.

    UPF_SKIP_TEST skips only the loopback test. This test could work on PXA,
    but requires PXA-specific pre-initialization. There are more test after
    the loopback one, which will fail if we are not on PXA. So I decided
    that skipping it is easier than tricky rewriting of autoconfig().
