Is it really?  What are the guarantees for the objfile architecture?

If an object is not sniffed as belonging to a particular os/abi, I
believe we won't get its tls address routine now, even when connected
to a target reporting the appropriate OS/ABI some other way or using
set arch.

This is not a big deal for Linux, since every linked object is
generally sniffable.  But I've been working with two other OS's
recently where our dependence on sniffers is a problem; neither
Symbian OS nor DICOS has clear markings.
