Build failure in procfs module

Hi folks,

I ran into a problem that might be triggered by Peter's recent
changes to procfs.  Namely, the buildworld procedure would fail in
the procfs module if MODULES_WITH_WORLD were set.  I noticed it
first in CURRENT and then tested it in a clean environment by
building a freshly CVSup'd RELENG_6 on a freshly installed 5.4-RELEASE,
with MODULES_WITH_WORLD set.  I think it's a route of upgrading
quite a few people will follow.

Here's the diagnostics:
