Local fix

Problem summary

• - With this fix,with _LARGE_FILES no compilation error
  

Problem conclusion

• - The `open` macro be replaced with an ASM label
  - During compilation time if _LARGE_FILES is enabled,
    it will append the asm label, which helps to create an alias
    for open ->open64 at assembly level during compile time.
  - During runtime, when _LARGE_FILES is enabled,
    when open is called it will invoke the opne64 system call.
  - Example :
    extern int open(const char *, int, ...) __asm__("open64");
  

Temporary fix
