Arch Linux

I am seeing warnings relating to a failure to set default locale when building with devtools 20220207-2. Both bsdtar and perl throw a similar warning. Shown below is attempting to build bleachbit-cli from the AUR.

Steps to reproduce:

% CHROOT=/scratch/chroot
% mkdir $CHROOT
% mkarchroot $CHROOT/root base-devel
% cd /scratch/bleachbit-cli
% makechrootpkg -c -r $CHROOT
