I have a choice either to leave it as is, and let it go to root of file system
(with broken empty values for user IDs), or let it go to some more or less
traditional place. /usr/local is traditional at least for autoconf-based
software, thus people can expect it going there.

The only way not to step on something already existing is to generate random
directory in $TMPDIR. This works, for sure, but it is rather unusual and 
surprising.
Do you have any better suggestion?

Alternatively, it is possible to bail out when directories are not supplied.

This change doesn't affect anything before you start using mk files outside 
pkgsrc
and you stop passing values of expected environment variables.
