freebsd stable - Apr 2018 - libmap non-absolute paths broken in 11.1-STABLE

Hi!

I've just updated my desktop from early 11.1-STABLE to recent one
11.1-STABLE
and found that non-absolute paths do not work anymore, like this:

libevent-2.0.so.5 compat/pkg/libevent-2.0.so.5.1.10

With luck, this still works:

libevent-2.0.so.5 /usr/local/lib/compat/pkg/libevent-2.0.so.5.1.10

Is this known problem?
