Yes, it looks like you put an archive file inside another archive
file.  The linker doesn't understand that.  Archive files that you
pass to the linker should only contain object files.

You can put the entire contents of one archive into another by doing
something like:

    mkdir tmp
    cd tmp
    ar x ../INNERARCHIVE
    ar rcv ../OUTERARCHIVE *.o
