[Xen-devel] [PATCH] build: fix clean rule to cover objects in unvisited subdirs

[Jonathan Creekmore <jonathan.creekmore@xxxxxxxxx>]

In commit 8b6ef9c152edceabecc7f90c811cd538a7b7a110,
several files in xen/common/compat were changed to be built
using the Makefile in xen/common, by appending the compat
prefix to the object files. Additionally, the
xen/common/compat directory was removed from the subdirs-y
variable, so it is no longer visited by the clean rule. This
resulted in some object files being built by inclusion into
obj-y, but not cleaned because they lived in a directory that
was unvisited by the clean rules. Appending obj-y to the clean
rule causes object files of this type to be cleaned up along
with files in the visited directory.
