I guess I have to spell things out once again.  Here's what I've done: Ran 4 builds each on Solaris/amd64 and Linux/x86_64, one pair with the `projects` layout, another with the `runtimes` layout, both with and without this patch.  Here's what I find (listing the target triple used, the `liborc_rt` location, run

As you can see, there's absolute no difference in behaviour between Linux and Solaris, as I've been saying all this time.  However, I'm beyond caring now: this patch at least makes the failure go away!
