New Revision: 238795
URL: http://svn.freebsd.org/changeset/base/238795
Log:
Try to avoid all files dependence on the modification time of the large and
often modified directory created symbolic links points to - it cause
unnecessary full rebuilds each time make runs when directory is changed.
So do it only if symbolic link does not exists, which usually means that
objdir is clean anyway.
