Makefile using cp -arf

[Michael Franz]

So, this is making copy of the openjdk directory with all the source files
being linked.  Any files created in this directory will be that, created.

Does linux have pax?  I have not used it, but it might be an option.

Is there away to change the copy command?  I can use another copy program
gcp - the GNU version, which should be the same as Linux, but has a
different name.  Wish I would have found this sooner.
