Likely in decl_default_tls_model.

That said, it seems that TLS_MODEL_EMULATED is used by varasm.c for
something else, namely for the artificial variables it creates.
It is something Nathan introduced for vxworks or something, I wasn't aware
of those changes until now.

So, perhaps instead the user decls even when emulated should use the
local/initial exec, local/global dynamic TLS models in SYMBOL_REF_TLS_MODEL.
I believe those symbols normally don't show up in the RTL IL, only in
debug_insns, and dwarf2out.c will handle it right in that case.
Thus just removing that !targetm.have_tls from the condition would suffice.
