+Subject: [PATCH] Remove modules_clean from clean target
+
+This is needed when building applications (w/o module)
+Since OE will run 'make clean' before reconfiguring, this
+will try to run module_clean and will wrongly try to look for removing
+modules from /lib/modules
+
+Upstream-Status: Inappropriate [ OE-Specific ]
