One drawback is this will make firmwares with really full flashes uncompilable. Do I understand it right that lld v7 doesn't require the workaround?

No, this also needed for the v7 I tested. Without the workaround linking with LLD fails with the error message in the comment; GNU LD can link the same program without errors and produces a binary that doesn't crash OpenOCD.

Are you going to look at the underlying lld bug? I don't yet use lld for my embedded development so I'm afraid you're in the better position here. I can review though.

I will at least submit a bug report. I have zero experience hacking LLVM :-).

fwiw, with arm-none-eabi-ld at least, this doesn't cause problems even when bss is larger than the entire flash space, everything works as it should (surprisingly?). I haven't tried with lld.
