Comment(by ppurka):
@jhpalmieri: I added -u to make sure that the second time `make install`
is run, cp does not go around copying the files all over again. The
options `-r`, `-v` were all present from before. `ln -f` was needed in
case the user ran `make install` yet again, otherwise ln would give error.
If the first invocation of make install doesn't fail, then there is no
need to use -f with ln.
If `cp` is unreliable then what is the alternative (it is actually quite
reliable on linux with the `-a` option, that is, it copies symlinks
properly)? Alternatively, can we assume that `rsync` is available on all
platforms and use rsync instead?
