This commit applies a patch for crashes when TERM isn't set:
https://gitlab.com/ilpianista/arch-audit/-/commit/5176a625fb5a6b4daf6be996d714c3cef001750f

We've decided to disable this hook, if you want to enable it,
either move it to /usr/share/libalpm/hooks/arch-audit.hook or symlink it to there.
The default directory for the hook will be /usr/share/arch-audit/arch-audit.hook from now.

When displaying upgradable packages, do not show packages not yet available in the repositories

FTR, commands used to change arch=() and then verify the changes:

$ sed -Ei "/^arch=/{s/ *?['\"]?i686['\"]? *?//;s/ *$//}" */*/PKGBUILD*

$ grep -r i686 * | grep arch= | grep -v repos

$ svn diff | grep -A 1 ^-[^-] | grep -v -- -- | cut -c2- |
  while IFS=$'\n' read -r l1; IFS=$'\n' read -r l2; do
    echo "$l1 -> $l2"
  done | sort -u
