First of all, the kernel Makefiles contain a hack which force
-fno-strict-aliasing whether you want it or not.

Second, the kernel will *not* build without -fno-strict-aliasing,
partly because of preexisting aliasing violations and partly because
of aliasing violations which were introduced after the hack (and could
have been avoided if that hack had not been in place).

not throughout the tree - only in the kernel.
