People patch their kernels to lie about the version, so I don't think
this is correct.

Kernel developers also think it's acceptable to change compatibility
mechanisms that have already been deployed in binutils or glibc, so I
really think this needs to wait until some signal has been added to the
the auxiliary vector in a mainline kernel.  Sorry.

Thanks,
Florian
