If we make the package depend on BR2_GCC_ENABLE_TLS, then it would no
longer be visible for any external toolchain.

I'm always a bit reluctant to add more and more toolchain options,
since they are a pain to maintain, and do not necessarily reflect real
use cases. Is it really an useful use-case to support non-TLS
toolchains on architectures where TLS support is available?
Best regards,
