Yes, this is due to a custom -mno-align-long-strings flag, which is only
supported by gcc in base.  I've conditionalized it in r279598, so please
try again after that.  You will also need this patch I just posted to
freebsd-current [1] for libnv: gcc reports the same error about an
ambiguous operator<< for one of its ATF tests.
