The `_gp_disp` is a magic symbol designates offset between start of function and gp pointer into GOT. Only `R_MIPS_HI16` and `R_MIPS_LO16` relocations are permitted with `_gp_disp`. The patch adds the `_gp_disp` as an ignored symbol and adjusts symbol value before call the `relocateOne` for `R_MIPS_HI16/LO16` relocations.
