/* If the including file requested it, also include the hwloc verbs
helper file. We can't just always include this file (even if we
know we have <infiniband/verbs.h>) because there are some inline
functions in that file that invoke ibv_* functions. Some linkers
(e.g., Solaris Studio Compilers) will instantiate those static
inline functions even if we don't use them, and therefore we need
to be able to resolve the ibv_* symbols at link time.
Since -libverbs is only specified in places where we use other
ibv_* functions (e.g., the OpenFabrics-based BTLs), that means that
linking random executables can/will fail (e.g., orterun).
