nit: I would still replace ${...} with $... (e.g. ${SYSCALLS_FILE} =>
$SYSCALLS_FILE) as I noted in v4 - readability. IMHO there is no need to use
${...} in whole script.

The same applies to include/lapi/syscalls/generate_arch.sh in the second commit.

nit: fixing space in /* */ comments (correct in the original regen.sh)
+ replacing old note about COPYING with SPDX in generated header:
