We can see the following definitions in bfd/elfnn-loongarch.c:
#define PLT_HEADER_INSNS 8
#define PLT_HEADER_SIZE (PLT_HEADER_INSNS * 4)
#define PLT_ENTRY_INSNS 4
#define PLT_ENTRY_SIZE (PLT_ENTRY_INSNS * 4)
so plt header size is 32 and plt entry size is 16 on LoongArch,
let us add LoongArch case in get_plt_sizes().
