	When all else fails, cat it all out to a file and grep for "Error code", and pray that you have enough useful context to find the actual problem that you need to resolve in order to make things work.
	Otherwise, you'll need to apply the patch for the PR noted to your source tree, (cd usr.bin/make; make clean depend all install), and then rerun your crossbuild.
