    or1k: add .note.GNU-stack section on linux
    
    In the OpenRISC build we get the following warning:
    
        ld: warning: __modsi3_s.o: missing .note.GNU-stack section implies executable stack
        ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
    
    Fix this by adding a .note.GNU-stack to indicate the stack does not need to be
    executable for the lib1funcs.
    
    Note, this is also needed for the upcoming glibc 2.41.
    
    libgcc/
            * config/or1k/lib1funcs.S: Add .note.GNU-stack section on linux.
