A second look at the log I see lto-wrapper failing, presumably in trying
to the test binaries.  I can duplicate the problem by adding -flto to
CFLAGS and CXXFLAGS. It _looks_ like lto-wrapper is invoking make
internally? 

Anyway, if you have an lto expert (or you are one), it would be
interesting to get feedback on what those error messages mean, and why
they are only triggered under make -j.
