           Summary: -mtune not supportd to the assembler
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

$ clang -c -Wa,-mtune=i686 conftest.c
clang: error: unsupported argument '-mtune=i686' to option '-Wa,'

To my surprise, GNU as actually has this flag. I'm not sure if there's anything
to wire it up to in MC (what does it actually do in GNU as?), but it'd be
useful if we didn't error on it.
