> These plugins have clear value to developers wishing to harden the kernel, and they are all free software (though many of them are GPLv2-only, meaning that they cannot be used to compile code needing the GCC runtime library; fortunately, the kernel does not use that library).

As far as I can tell, there are a handful of architectures that appear to link against libgcc. Are they going to find themselves in trouble here?

if an arch's vmlinux links to code from libgcc that is under the 'GCC Runtime Library Exception' (not all the code of libgcc is under that license) then it will not have met the 'Eligible Compilation' condition and the end result cannot be propagated.
