commit d7e06450b9d730d7b62ba52f611585810fa902df

    BZ #15711: Avoid circular dependency for syscall.h
    
    The generated header is compiled with `-ffreestanding' to avoid any
    circular dependencies against the installed implementation headers.
    Such a dependency would require the implementation header to be
    installed before the generated header could be built (See bug 15711).
    In current practice the generated header dependencies do not include
    any of the implementation headers removed by the use of `-ffreestanding'.
