Hmm, maybe I'm seeing a problem where there isn't one, but in case I'm
not: how will this work if there is more than one offloading compiler
configured? Won't you get conflicting -B paths added to
offload_additional_options in this case?

What we're doing in OpenACC offloading testing (gomp-4_0-branch), is in
the libgomp.oacc-c/c.exp (etc.) file cycle through all the available
offloading devices, and then in there -- I think -- such options should
be set, that are specific to one particular offloading device/compiler?

Thomas
