According to linker warnings, both GCC and LLVM generate '.rel.dyn' symbols:
mips-alpine-linux-musl-ld: warning: orphan section `.rel.dyn' from `init/main.o' being placed in section `.rel.dyn'
Link-time assertion shows that this section is sometimes empty, sometimes not, depending on machine bitness and the compiler [0]:
LD .tmp_vmlinux.kallsyms1 mips64-linux-gnu-ld: Unexpected run-time relocations (.rel) detected!
Just use the ARM64 approach and declare it in vmlinux.lds.S closer to __init_end.
