Please check the upstream Bug report (http://savannah.gnu.org/bugs/?53152). The analyses showed that -Orecurse / -Otarget are not the cause of the issue. The actual bug is, that make does not wake up correctly sometimes and the hidden dependency in the test triggers this. -Orecurse/-Otarget just change the timing to make it more likely in this special case. Please disable the test instead if disabling -Orecurse / -Otarget, as suggested in the upstream bug report comments.
