Oh, I didn't even know they finally introduced -Werror... Good.

If it is in the way maybe KCFLAGS=-Wno-error or similar may serve as a
workaround? Or KBUILD_ENABLE_EXTRA_GCC_CHECKS="" ?

Cf. Documentation/kbuild/kbuild.txt

You didn't say what kernel version - I just went to LXR for the latest.

Not that I know of. The minimal versions of everything needed are in
Documentation/Changes. I guess you are not interested in "minimal".

I would be very much surprised if the kernel could not be built with
gcc-4.6 - this is stock on Fedora, so lots of people must be using it.
Maybe not on PowerPC, though
