Subject: Illegal instruction on running vaultwarden on RPI (aarch64)

Hi All,

I'm trying to run vaultwarden (tried 1.33.2-r0 and 1.34.1-r1) on a
RaspberryPi 4 (aarch64).  This used to work fine, but as of upgrading
from alpine 3.21 to 3.22, I get an 'Illegal instruction' error whenever
I try to execute the main binary:

```
$ /usr/bin/vaultwarden
Illegal instruction
```

I initially thought this might be a packaging bug but I'm certain I
used to run successfully the older 1.33.2-r0 prior to recently
upgrading to alpine 3.22.  Instead then I'm inclined to believe that
something else *weird* is going on on this system.  Nothing sinister,
but I haven't been running alpine long and this was my first attempt at
upgrading in place. Maybe I missed a step?  I'm fairly sure I followed
the regular upgrade instructions, followed by upgrading the kernel and
initramfs:

Does anyone have any thoughts for how to begin to debug this?  I would
think that building vaultwarden from source might be the way to go
initially, but this is a rather resource constrained system.  I have in
fact tried building it, but even with generous swap space and single
threaded building (cargo build -j 1) it gets oomkilled.

This whole thing is written in rust of course, I know very little about
rust. Maybe this is a glaringly obvious issue to someone else.

I would massively appreciate any ideas, sucks to be without your
password manager!

Thanks
Max
