    LoongArch: testsuite:Fixed a bug that added a target check error.
    
    After the code is committed in r14-6948, GCC regression testing on some
    architectures will produce the following error:
    
    "error executing dg-final: unknown effective target keyword `loongarch*-*-*'"
    
    gcc/testsuite/ChangeLog:
    
            * lib/target-supports.exp: Removed an issue with "target keyword"
            checking errors on LoongArch architecture.
