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

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