The install of rdma-core is one way .. setting an exclude= is another.
I have seen instances where installing rdma-core tries to pull in some
i686 packages, depending on what all is installed on the machine .. but
the --exclude='*.i686'   (or *.ppc in the case of ppc64 tree) should
alwys work.

Regardless, they need to fix yum so it does not try to install BOTH
arches on a multi arch setup, unless multilib_support is set to all.
