[PATCH] RISCV-V: Add new relocation type for global array accesses with non-constant indices

[Kito Cheng]

Hi Li Qin:

You don't need INTERNAL_ variant of relocation, INTERNAL_ relocation
are used only when we need an relocation but it's not defined in
psABI, and it generally will generated during static link time and
discard/resolved at static link time.

And in this case, we will add new relocation type in psABI side, so no
INTERNAL_ relocation is not needed :)
