New Revision: 325466
URL: https://svnweb.freebsd.org/changeset/base/325466

Log:
  Default GCOV_PREFIX to DESTDIR, use gather_coverage from DESTDIR, etc
  
  This works by itself, when not executed as kyua, but unfortunately there's
  something in the atf/kyua stack that's preventing GCOV_PREFIX from being
  passed down, so, programs are failing with EPERM issues when trying to look
  for .gcda files and write to .gcno files on the host.
