On some devices (In my case a Lenovo Ideapad 100s-11iby) have 64 bit
processors, but a 32-bit UEFI, so the 64-bit installation mediums are not
recognized by it. 

Steps to Reproduce:
1. Grab a device with a 64-bit processor and a 32-bit UEFI
2. Try to boot from a 64-bit installation medium
Actual Results:  
The installation medium is not listed in the boot menu.

Expected Results:  
The installation medium is listed correctly, just like on a machine with a
64-bit UEFI.

I did a bit of research, and found out the following:
Fedora has natively supported 32-bit UEFI for 64 bit installs since Fedora 27.
There seems to be a a workaround, but this is not very practical for new users,
which adds a file from Github
(https://github.com/hirotakaster/baytail-bootia32.efi) to the installation


Could x86_64 installation media contain this file on the installation media in
the EFI partition:

It should be copied from /usr/share/efi/i586/grub.efi from grub2-i386-efi
package, the same as is EFI/boot/bootx64.efi from grub2-x86_64-efi.

This will add support for 32bit FW with 64-bit CPUs. It used to work fine when
I tried last time on such a machine. I had EFI/boot/bootia32.efi on an USB
stick and loaded config from a DVD. Then continued the installation the usual
