So you have a command that fails

...and a command that works. 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.
