TLS and single/posix thread model in gcc for genode

By default, gcc compiled by toolchain says that thread model is single.
Is it correct? In particular, what’s with TLS (thread local storage), do we need TLS being enabled via —enable-tls option?
I run some programs with TLS support in multi thread environments (golang runtime)... now it have a race when variable which should be in TLS (in accordance with comments, like in getg() current g) sometimes return null. I am not sure - may be this is related to TLS support, may be in locking...
If I try just to add option --enable-threads=posix
toolchain compilation stop giving Error

./gthr-default.h:35:10: fatal error: pthread.h: No such file or directory

Any suggestions? Should TLS work in genode over Nova “as it is”?
