rdma -devel packages missing (?) on f27/armv7hl, builds failing

[Kaleb S. KEITHLEY]

I've built glusterfs previously on F27 with these same Build-Requires. 
Same package & same .spec build on F28 and F26.

While trying to build a new version for the last 24 hours I keep hitting 
this:

...
DEBUG util.py:439:  No matching package to install: 'libibverbs-devel'
DEBUG util.py:439:  No matching package to install: 'librdmacm-devel >= 
1.0.15'
...

Thanks,
