RISC-V: Stop using LOCAL for the uaccess fixups

LLVM's integrated assembler doesn't support the LOCAL directive, which we're using when generating our uaccess fixup tables. Luckily the table fragment is small enough that there's only one internal symbol, so using a relative symbol reference doesn't really complicate anything.
