In OMPI 1.9a1r32604 I get much better results:
$ time mpirun --mca oob_tcp_if_include ib0 -np 1 ./hello_c
Hello, world, I am 0 of 1, (Open MPI v1.9a1, package: Open MPI

I enclosure 2 files with output of two foloowing commands (OMPI 1.9a1r32570)
$time mpirun --leave-session-attached -mca oob_base_verbose 100 -np 1 ./hello_c

$time mpirun --leave-session-attached -mca oob_base_verbose
How bizarre. Please add "--leave-session-attached -mca oob_base_verbose 100" to
your cmd line

I think something may be messed up with your installation. I went ahead and
tested this on a Slurm 2.5.4 cluster, and got the following:
$ time mpirun -np 1 --host bend001 ./hello
Hello, World, I am 0 of 1 [0 local peers]: get_cpubind: 0 bitmap 0,12

Here is my time results:

I'm also puzzled by your timing statement - I can't replicate it:
07:41:43 $ time mpirun -n 1 ./hello_c

Hi,
The default delimiter is ";" . You can change delimiter with
mca_base_env_list_delimiter.
