Well, the regular MIPS ISA has no PC-relative addressing mode (except
from branch instructions), so this can't be done with that instruction set
(the MIPS16 and microMIPS ISAs do have some forms of PC-relative
addressing, which can be used to access hidden and internal symbols
bypassing GOT in PIC code if the compiler is smart enough).
