I'd say so, perhaps with the exception of Solaris where I'd leave that to
the target maintainer to decide.
The other alternative is to have the TLS symbols included everywhere and add
some magic to the abi checking scripts/proglet which would detect the
emulated TLS configuration and not error out if the TLS symbols disappear,
probably better long term, but supposedly too late for 4.9 for now.
