make TAGS broken with commit 99443f811c452c6 ("scripts/tags.sh: change find_other_sources()...")

[Sebastian Ott]

Hi,

on my s390 test system make TAGS is broken since commit 99443f811c452c6
("scripts/tags.sh: change find_other_sources() for include directories")

# make TAGS
  GEN     TAGS
xargs: etags: terminated by signal 11

This is a rather old etags from fedora 24. On x86 using a more recent
etags (fedora 27) make TAGS works as expected. I'll try to update the
test system maybe that'll fix the problem..

Regards,
Sebastian
