cmd/link: recognize the new R_LARCH_32_PCREL type on loong64

Browse source 
Due to the latest binutils change [1], at least for certain 32-bit
relocs in .eh_frame section, this new type of relocation record is
emitted, leading to breakage on systems with bleeding-edge toolchain
when trying to link with object(s) with such new-style relocs.

Simply treating it the same as the existing reloc types seems enough.

Fixes #54222
