Yes. Although the patch fixes a more serious build/make check issue
with --disable-guest-agent, the inadvertant commenting in bab47d9a75a
(which was probably to work around that bug) masks the build failures
by unconditionally disabling the test.

Since disabling the unit test is a late regression, I think it's
probably worthwhile to try to fix as long as it isn't holding up
the release. Will send a pull shortly.
