So you can start "bisecting" between these two: Try removing -j5 or ARCH= or CROSS_COMPILE= from the make command line. Still failing? Add 'printenv >env.make' to the tags.sh script and run it via make tags. Compare the env.make file with printenv output from the shell. Try setting the variables from env.make in the shell and see when ./scripts/tags.sh gtags starts failing. FWIW, both your commands seem to work for me and produce a GRTAGS that is 256MB big.
