Pasha added configure switches for this about a week ago:

I like these flags but I thought there was going to be a run time
check for cases where Open MPI is built on a system that has ibcm
support but is later run on a system without ibcm support.
Yes, there are.
- if the /dev/infiniband/ucm* files aren't there, we silently return
"not supported" and skip ibcm
- if ib_cm_open_device() (the first function call) fails, we assume
that IBCM simply isn't supported on this platform and silently return
"not supported" and skip ibcm
