Another option would be to use debirf to build an initramfs-based live
system that looks like your normal system (minus logs/data/config),
runs entirely from RAM and contains fsck and any other tools needed
for rescuing the system. I'm not sure if it can do cross-arch builds
but failing that you could build it on the ARM system you have.

It should be feasible to download the source package, tweak the build
config, rebuild the binary packages, extract the relevant binaries and
include them in your small Linux image.
apt build-dep busybox
apt source busybox
cd busybox-*/
$EDITOR <busybox-build-configs>
dpkg-buildpackage
cd ..
dpkg-deb -x busybox-static*.deb busybox-static
cp busybox-static/bin/busybox /srv/tftp/

You would have to either build it or get someone else to do that for you.
You could use the one from the normal fsck packages instead of busybox.
I don't know how big the busybox fdisk/fsck support is, but it might
be worth reporting a bug on busybox asking for them to be enabled.
Alternatively, a bug report asking for a busybox-static-full package
containing support for every busybox applet might be a good idea.
