Rebuild against freerdp2 as project is not yet compatible with freerdp > 3.

Add patch to remove neatvnc upper bound check, since it seems to work with 0.8.0:
https://gitlab.freedesktop.org/wayland/weston/-/issues/890

Add all direct library dependencies.

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

- fix FS#52596
