    LoongArch: The symbol got type can only be obtained after initialization
    
    When scanning relocations and determining whether TLS type transition is
    possible, it will try to obtain the symbol got type. If the symbol got
    type record has not yet been allocated space and initialized, it will
    cause ld to crash. So when uninitialized, the symbol is set to GOT_UNKNOWN.
    
    (cherry picked from commit b221bff7c7ca20d961a7e6b663a545384054a5be)
