[PATCH v3] RISC-V: Fix IFUNC resolver cannot access gp pointer

[Kito Cheng]

Hi everyone:

I support this approach rather than adding DT_RISCV_GP_VALUE, I
cooperated with YangYu to try that approach, and found that basically
repeat the code as checking "__global_pointer$" and then initialize
the gp.

As Yangyu mentioned before, we have mandatory "__global_pointer$"
symbol[1] must be exported if executables has enabled GP relaxation,
so I think it enough guarantee from the psABI aspec.
