As bootstrap code gets improved (KASLR, more complex decompression, etc. etc.) we keep using new bits of generic facilities... So this should definitely not be hidden by open coding that function (which has various other disadvantages as well), but should be turned from silent breakage either into non-breakage (and do so not only for sort() but for other generic functions as well), or should be turned into a build failure.
