[PATCH-for-10.2] roms: Do not try to build EDK2 for 32-bit ARM on Fedora

[Philippe Mathieu-Daudé]

With Fedora 27, support for 32-bit ARM hosts was dropped.
QEMU also stopped building the docker images in commit
0054dc8bde4 ("Update lcitool and fedora to 37").

/me fails to see the link to the patch ...

This is about the /guest/ firmware images, and they are
cross-compiled.  And note that you can run 32-bit guests
on 64-bit hosts (if supported by the cpu).

Note that I have no objections to removing the 32-bit edk2
firmware images.  Upstream edk2 is in the process of removing
32-bit support, so that is going to happen sooner or later
anyway (for both arm and ia32).  Also UEFI on 32-bit never
really took off in the first place.

But when doing so do it properly please.  Remove build config
(in edk2-build.config), pre-built binaries, maybe also test
cases, ...

take care,
  Gerd

I only have handy Fedora 42 and 43 VMs where this script doesn't
work anymore. I'm not really interested in installing a pre-37
Fedora to build EDK2 ARM, nor motivated right now to clean this
"properly". Better we wait EDK2 32-bit removal upstream and then
clean these QEMU scripts.

Regards,

Phil.
