If you get warning messages about x86 you can ignore them. Here's an example of one:

WARNING: Unable to find a suitable destination to install 32-bit compatibility libraries. Your system may not be set up for 32-bit compatibility. 32-bit compatibility files will not be installed; if you wish

[Cto install them, re-run the installation and set a valid directory with the --compat32-libdir option

Install OpenCL runtime (not required but why not, use those CPUs too)
