If it does not cost too much to keep make kernel style of build working, then it should be kept. In this case, the only requirement is to merge lex changes to stable branches. This is what I suggested (or requested, depending on how you interpret my mood). The lex backporting is orthogonal to the issue whether the lex shall become build tool.
