    libstdc++: Make permissions_are_testable function inline [PR90787]
    
    This function should be inline, so that's it's not emitted in tests that
    don't use it, to avoid undefined references to geteuid().
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/90787
            * testsuite/util/testsuite_fs.h (permissions_are_testable):
            Define as inline.
