Some of the Debian automatic builds are failing apparently because the
build-arch and build-indep targets are being called in parallel and they
are both attempting to rebuild tests/testsuite at the same time, which
doesn't work. We could make the OVS makefiles handle this particular case,
but in general it's not a good idea to independently invoke a single
makefile multiples times in parallel, so this commit avoids that problem.
This also dumps the DEB_BUILD_OPTIONS variable to the log, because there
doesn't appear to be any way to infer it from the automatic builders'
log files.
