Build error: undefined symbols in gcc plugins

[fmarier]

I'm getting compilations errors on Debian sid amd64 with the latest 3.3.6 kernel and grsecurity-2.9-3.3.6-201205130001.patch:

I've just done a "make clean" and "ccache --clear" but I'm still getting these errors. Are there any other details I can give you to make this a more useful bug report? (I feel like this is very light on details, but I'm not sure I should paste my whole config and build log...)

$ gcc --version
