Subject: [PATCH v9 2/6] riscv: Move .rela.dyn outside of init to avoid empty relocations

This is a preparatory patch for relocatable kernels: .rela.dyn should be
in .init but doing so actually produces empty relocations, so this should
be a temporary commit until we find a solution.

This issue was reported here [1].
