[MLIR] Temporary workaround for calling the LLD ELF driver as-a-lib

This fixes the situation described in https://github.com/llvm/llvm-project/issues/53475 with a repro exposed by https://github.com/ROCmSoftwarePlatform/D108850-lld-bug-reproduction

This is purposely just a workaround to unblock users. This could be transplanted to the release/14.x branch if need be. A proper fix will later be provided in https://reviews.llvm.org/D119049.
