It might be a problem with different 'make' versions, or something else in the environment that leads to "-Wno-frame-address" not being set on the command line instead.

I'm using "GNU Make 4.1" - this is all just the default Debian stuff, I've not customized my x86 host environment.

Make 4.2.1 here with gcc 7.2.1 and I get tons of build warnings on my 3.18.y tree on my laptop, but my build machine running Fedora (make 4.2.1 and gcc 7.2.1) I get no build warnings at all.

I've given up trying to track it down for my laptop, something is preventing the compiler flag from being added to the gcc command line, and I don't care anymore...

thanks,
