[PATCH 2/2] RISC-V: reloc: ignore R_RISCV_NONE relocations

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

When linking a position independent executable, the linker may reserve
a dynamic relocation slot for a reference to an absolute symbol and only
later determine that no runtime relocation is needed. The slot is not
removed, but turned into an R_RISCV_NONE entry, which must be ignored.
