@echristo: Do you think you might be able to help review this?

By way of background: RISC-V compilers are strongly encouraged to make use of linker relaxation. The compiler might generate a pair of instructions to call a function, but the linker may be able to delete one once the final code layout is known. In order for the linker to do this, relocations must be generated for everything - local control flow, symbol differences, debug info.
