[openmp] Drop requirement on library path environment variables

Involves multiple independent changes, intent is to land one piece at a time.
This diff provides a big picture of one way to avoid needing to specify
LD_LIBRARY_PATH and/or LIBRARY_PATH in order to run any openmp offloading code.
Specific details of the implementation are not necessarily interesting - e.g.
dlinfo appears to be impossible to use safely, so will drop that.

This diff (and associated openmp-dev email to be written shortly) is to start
a discussion on whether requiring users to set LD_LIBRARY_PATH in order to run
any openmp application is what we want.

Reviewers are a guess at interested parties, feel free to add anyone else.
