linux-user: Add i386 TLS setter
We can easily set the TLS on i386. Add code to do so. Signed-off-by: Alexander Graf <agraf@suse.de> [PMM: also remove "target_nptl=no" line from configure, for consistency with other patches in this series] Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
