Hmmm, when I build with gcc-10.2 now it doesn’t complain about the size … but before it certainly did! (would give the same message about not fitting in region). Too bad my Lich is now dead, so I can’t test anything any more 
Which parts are failing on that script? I know it’s not a pretty setup, but it should work.
Lich is undying by definition! See how to force bootloader on Lich
Regarding plugdata build errors, first of all it gets a 404 when downloading http://ftp.de.debian.org/debian/pool/main/a/alsa-lib/libasound2_1.1.3-5_amd64.deb .

Btw, I’m running Gentoo on aarch64, so the file would be fairly useless 
After compiling OWL libs it thows the following:
~/dev/rebeltech/plugdata-heavy-toolchain/OwlProgram ~/dev/rebeltech/plugdata-heavy-toolchain
In file included from LibSource/ColourScreenPatch.cpp:6:
./Source/PatchProcessor.h:5:10: fatal error: Patch.h: No such file or directory
5 | #include "Patch.h"
| ^~~~~~~~~
compilation terminated.
make: *** [compile.mk:202: Build/ColourScreenPatch.o] Error 1
I guess it doesn’t see it in OwlProgram/LibSource/ for whatever reason.
There was another error, but turns out it was caused by not running it in virtualenv.
No it’s totally fried. When I plug it in it just completely burns up and is totally unresponsive.
Ah, yes the toolchain is not at all tested on arm64 Linux, this will certainly require additional work 
You might test if your OWL digital board is functional by powering it from USB. If not, then you might have to replace it. Otherwise something related to power supply is not working, likely on Lich itself. Might be a dead power regulator, might be something else.
Yeah it does show up, but gets very hot and then after a while disconnects:

etc ..
Will contact Befaco about replacing or upgrading the board.
Finally got a replacement/upgrade OWL board (v3).
So I’ll circle back on this effort soon-ish.
@antisvin btw before we could support aarch64 Linux we need to find an alternative for the build-anywhere tools that we currently use. This project is for x86 only and is anyway quite outdated. Hasn’t seen activity in years and has quite some old tools.
For aarch64 we indeed would need to make some platform-specific changes as well.
