[Portland] DESTDIR support for xdg-utils

Current versions have --mode user|system and default to something sane
based on the UID of the caller. Does that help you?

I'm not sure. It seems that you are trying to run a post-install hook as
part of the package building process. I'm not sure I understand why you
want to do that. If you run this part truly post-installation you will
not run into these problems. Doesn't gentoo provide facilities for that?
