Per ziglang/zig#22685 (comment), Zig 0.14 has enabled 'unwind tables' for ARM embedded (and most other platforms). Therefore it looks like we need to update tools/generate_linker_script.zig, as part of the upgrade to Zig 0.14 (being done on the current zig-master branch).

I have no idea whether something similar would be needed for RISCV, and/or for other embedded platforms.
