Commit2027e99e61("Makefile: Run defconfig files through the C preprocessor") adds `generated_defconfig' file, but fails to clean that up. It might be useful to have that file around after `make' is done, but it's better to clean that up on `make clean'. Also we probably want to hide it in `git status' list. This patch makes the described changes, and also adds `-P' parameter to the CPP command that produces the `generated_defconfig' to avoid generating linemarkers.

# We are using a recursive build, so we need to do a little thinking
|
|
# to get the ordering right.
|
|
#
|
|
# Most importantly: sub-Makefiles should only ever modify files in
|
|
# their own directory. If in some directory we have a dependency on
|
|
# a file in another dir (which doesn't happen often, but it's often
|
|
# unavoidable when linking the built-in.o targets which finally
|
|
# turn into vmlinux), we will call a sub make in that other dir, and
|
|
# after that we are sure that everything which is in that other dir
|
|
# is now up to date.
|
|
#
|
|
# The only cases where we need to modify files which have global
|
|
# effects are thus separated out and done before the recursive
|
|
# descending is started. They are now explicitly listed as the
|
|
# prepare rule.

|
|
#
|
