Error on compile Glibc 2.34 (32 bit) on 64 bit

For some CentOS packages, you need to use the i386/i686 buildroot and
mock, not an installed operating system.  The --target option does not
work with all packages.

The buildroot is published here:

  <https://kojihub.stream.centos.org/kojifiles/repos/c9s-build/latest/i386/>

I'm including a possible mock configuration file below.

Thanks,
Florian
