RHEL/CentOS always installs both 32-bit and 64-bit libraries, that is
the way Red Hat wanted it, so Applications designed only as 32-bit can
run without any modification on 64-bit system. If you check other
packages, you will see many have 32-bit counterparts.
This is normal behavior without any repercussions, so unless you intend
to remove all 32-bit libraries from your system, I recommend to go ahead
and install both 32-bit and 64-bit packages.
