A new set of relocation types was added in the LoongArch ELF psABI v2.00 spec [1], [2] to replace the stack-based scheme in v1.00. Toolchain support is available from binutils 2.40 and gcc 13 onwards. This patch adds support for the new relocation types, that are simpler to handle (in particular, stack operations are gone). Support for the v1.00 relocs are kept for now, for compatibility with older toolchains.
