debug/elf,cmd/link: add additional relocations for loong64
The Linker Relaxation feature on Loong64 is already supported in binutils 2.41.
The intermediate code generated after enabling this feature introduces three
reloc types R_LARCH_B26, R_LARCH_ADD32 and R_LARCH_SUB32.
The other relocation types are not currently used when running all.bash, but
in order to avoid the host tool chain making the decision to use it we don't
have to catch it every time.
The LoongArch ABI at here:
