HP aCC does not accept any of the previously tested CC_LD_DYNPATH
formats, but only its own[1] "-Wl,+b" format. Add it to configure.ac.

1. http://nixdoc.net/man-pages/hp-ux/man1/ld_pa.1.html

I took the liberty of slightly amending the commit message.

I can see that this one has not yet been committed nor my PR has been 
pulled.

Any chances to get this into master?

Sorry, it jsut fell of the cracks.  The way the new test was added
looks very good --- any platform that is happy with the existing
test will continue to function the same way, and a platform that
knows -Wl,+b would use it instead of failing.

Will pick it up.

Thanks.
