With GCC 4.8.0 (linux host and target) this command works:
$ gcc -Wall -Werror -Wno-format-nonliteral test.c
This doesn't:
$ gcc -Wall -Werror -Wformat-nonliteral -Wno-format test.c
cc1: error: -Wformat-nonliteral ignored without -Wformat
[-Werror=format-nonliteral]
cc1: all warnings being treated as errors

Interesting fact - this command works too:
$ gcc -Wall -Werror -Wformat-nonliteral -Wno-format-nonliteral test.c
I've tested that it in fact disables checking of non-literal format strings,
but it "looks bad" - like a hack (;

So I think the solution is to change "-Wformat-nonliteral" to
"-Wno-format-nonliteral" instead of adding "-Wno-format". Another possible
option is to add "-Wno-format-nonliteral" instead of "-Wno-format"...

<just saw the new comment>

I was thinking about the same thing - I'll try that in a moment and report
back.
