Comment:

 As shipped, the makefile does nothing in the `all` rule, other than depend
 on `TARG`. So I fixed the problem in r87788 by adding a step to the `all`
 rule to change the modification time of the object and library directories
 to an earlier time, namely the time the makefile was modified (it seemed
 as good a time as any). That way, by the time the `install` rule is
 called, the library directory will be older than the libraries, so a
 rebuild won't occur. I have never seen a makefile do this, and I know
 plenty of makefiles that create directories, so I feel like there must be
 an easier or better solution, but I don't know it. I have a feeling it
 might involve not using rules to represent directory creations, but
 changing that is more re-engineering than I wanted to get into right now.
