This hunk was added to avoid accidental overwrite of the top Makefile
in case O= points to the top of the source tree.
As commit
4f1127e20437 ("kbuild: fix infinite make recursion"),
it caused some troubles in the past because Kbuild assumes O=
as out-of-tree build, while it actually works in the source tree.
Now this works more properly; if O= points to the source directory,
it is handled as in-tree build. So, this sanity check is unneeded.

# Usage
# $1 - Kernel src directory
-# Only overwrite automatically generated Makefiles
-# (so we do not overwrite kernel Makefile)
-if test -e Makefile && ! grep -q Automatically Makefile
-then
- exit 0
-fi
if [ "${quiet}" != "silent_" ]; then
echo " GEN Makefile"
