You can't, it's not a use case we support.
To further this piece, you would need to have code changes in rpm, dnf,
yum,
packagekit, mock and everything else dealing with rpm installation and
removal. none of the tooling supports what you are asking.
That must be some very recent code. I can confirm that CentOS 7
armv7hl works just fine with just the /etc/rpm/platform configured
appropriately in the chroot on an aarch64 host (with a non-default
kernel built with 4KB pages). No dnf, granted, since that is more
recent than F19, but all the rest of it works just fine.
So unless there has been a lot of bit rot since F19, it seems
unlikely any of the rest of it would need fixing.
Some aarch64 hardware will not run 32 bit binaries at all. when we
started on
the path of supporting aarch64 we mad a concious decision not to
support
running armhfp or arm 32 bit binaries on 64 bit environments. the
supported
way to run 32 bit binaries is to do so in a 32 bit vm.
Unless I am missing something, even ignoring the very non-trivial
performance hit of running in a VM, if the hardware doesn't support
the 32-bit instruction set, then the VMs won't work either, so I'm
not sure what the point being made here is.
