This is a harmless side effect of using "&&" in conjuction with test(1).  
It's "normal" for the way the Makefile is written in those directories.  
(Changing these to `if' statements would remove these messages.)

Some of the mtree input files conflict with each other.  Again, this is 
harmless; there is at least on PR that mentions conflicts like this.

... usually because /usr/obj is a file or a symlink.  This is not an 
error for the build process, even though mtree exits with 2 because it 
couldn't do everything it was asked.
