Description:
can makepkg please not run commands passed in the $PACMAN environment variable as root
but only run the command itself?

Additional info:
when developing a AUR package it is convenient to run a command to install dependencies.
so i set
export PACMAN=paru

running package builds from AUR as root is (fortunately) prohibited by AUR helpsers
like yay and paru. but - that means - it does not work seamlessly with makepkg, as
it tries to call the command given by $PACMAN as root. much nicer it would be that
the command provided needs to make sure it has appropriate permissions, either via
a "sudo command" or something inside, like in yay and paru.
