What does "system language" mean?

Question

The Go talk 2009 pdf contains a comment to explain why they came up with the go language:

No new major systems language in a decade.

What is the meaning of a system language?

• Is this the language that should run on the target system, generating its own binary?
• Is it a language that can independently create an operating system?

I see that C # / Java is not a "system" language, but C / C ++ is that.
