This was mostly done by avilla and bapt back in the days because
update-mime-database or something else that touched $HOME was being
called during the build or installation.

I'd say if svn blaming the changes to bsd.port.mk shows they're more
recent than those changes to XDG_* variables in the Makefiles (and your
tests still work), then we can go ahead.

bapt, do you have anything to add here?
