  Log Message:
  -----------
  [RISCV] Pass -u to linker correctly.

`-u` is a linker option used to pretend a symbol is undefined,
this option are common used for forcing archive member extraction.

This option should pass to `ld`, and many other toolchain in Clang
like `tools::gnutools` has pass that too.
