svn commit: r338098 - in head: . tools/build

[Alex Richardson]

New Revision: 338098
URL: https://svnweb.freebsd.org/changeset/base/338098

Log:
  Don't create directories in ${WORLDTMP}/legacy with mtree
  
  This has two advantages:
  1) We no longer create lots of empty directories that are not needed
  2) This is a requirement for building on non-FreeBSD hosts since mtree will
  only exist after the bootstrap-tools phase there.
