    build: silence GNU ld warning about executable stacks
    
    While for C files the compiler is supposed to arrange for emitting
    respective information, for assembly sources we're responsible ourselves.
    Present GNU ld master started warning about such, and hence 2.39 is
    anticipated to have this warning.
