    compiler-gcc.h: __nostackprotector needs gcc-4.4 and up
    
    Gcc versions before 4.4 do not recognize the __optimize__ compiler
    attribute:
    
        warning: ‘__optimize__’ attribute directive ignored
    
    Fixes: 7375ae3a0b79ea07 ("compiler-gcc.h: Introduce __nostackprotector function attribute")
