The best way to answer all of these questions is to see what Solaris ld
actually does.

That said, I don't see any reason that the libraries must exist at link
time.

I assume so.

I assume as specific on the command line if there is no soname.

I doubt it ld would search those directories by default, but I really
don't know.

I don't see why not.
