Both ignoring it on non-i386 and not restricting it would seem fine to me. LLD, when it parses import libraries in `ImportFile::parse`, doesn't restrict `IMPORT_NAME_NOPREFIX` to i386, so I did the same here.

I think this is fine, I don't think we need to explicitly restrict the handling of this case to i386 - if one crafts an import library for another architecture that says `NOPREFIX`, I think it is fine to try to run that logic.
