I've had the same issue teeing make output for coverage measurements.
A better way to write this might be

src-kernel: src-kernel-tools
	rm -f src-kernel-done
	{ cd src; ./amd64-kernel.sh 2>&1 && touch src-kernel-done; } | tee build_amd64_kernel.log
	rm src-kernel-done

You really want to catch all failures, including tee failures.
