These flags controls if there should be bitcode embedded in the object file.
For the case of LTO, there is no object file thus there is no embedding.
If change the meaning of this flag, it will complicate the logic around line
6355 and 4169. The other option is to add another flag but it seems little too
much for passing one flag to ld.
