[riscv] Disable linker relaxations when linking with ld.lld
We have to compile RISC-V code with -mno-relax when linking with ld.lld
since ld.lld does not yet support RISC-V linker relaxations. Without this
change, linking with ld.lld results in many errors such as:
`relocation R_RISCV_ALIGN requires unimplemented linker relaxation`.
This support was implemented as part of LLVM 15, but to support older
versions of ld.lld we add the flag unconditionally for now.
