    ld: Don't use -mdirect-extern-access for LoongArch
    
    Don't check DIRECT_EXTERN_ACCESS_CFLAGS/NO_DIRECT_EXTERN_ACCESS_CFLAGS
    for LoongArch since -mdirect-extern-access on LoongArch works only
    without dynamic linker.
    
            PR ld/33409
            * testsuite/config/default.exp (DIRECT_EXTERN_ACCESS_CFLAGS):
            Skip on LoongArch.
            (NO_DIRECT_EXTERN_ACCESS_CFLAGS): Likewise.
