Why is this change needed? Especially the -e s/x86_64/x86. It causes UML to get build for x86 which is a nasty change of the default behavior.
Before your change you got a UML kernel for the underlying arch just by running "make linux ARCH=um". Now it will always build a x86 UML kernel, also if you run it on x86_64 and one is forced to override SUBARCH by hand.
