Fixes <http://bugs.gnu.org/26949>. Reported by Pjotr Prins <pjotr.public12@thebird.nl>. * guix/build/union.scm (file-is-directory?): Return #f when FILE does not exist or is a dangling symlink. (file=?): Pass #f as a second argument to 'stat'; return #f when both ST1 or ST2 is #f. * tests/profiles.scm (test-equalm): New macro. ("union vs. dangling symlink"): New test.
