I haven't found anything specifically about this error message, but it looks vaguely like the amd64-specific messages that happen when trying to link non-PIC object files into a shared library. In src/lib/libc/aarch64/gen/sigsetjmp.S, we have two conditional jumps b.eq C_LABEL(_setjmp) [...] b.eq C_LABEL(_longjmp) Maybe there's a simple macro change that can make these relocatable jumps. Alternatively, we could probably simplify the code by merging setjmp.S and sigsetjmp.S, so that PC-relative jumps could be used. I'm going to be AFK for the next couple days, and I do not have arm64 hardware, so I hope this is enough information for someone to work out a simple fix.
