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.
