That's not necessarily a contradiction. Writing being not allowed
doesn't imply that the directory must not exist.

The problem is that apart from T (and maybe HOME), there seems to be
no other directory that check_reqs.eclass could use for its disk space
check in pkg_pretend. WORKDIR doesn't exist in pkg_* phases.
