The out-of-tree build is broken in 'make deb-pkg'. The
header checks and the header install works on the source and
not on the object tree.
While fixing this also replace the direct 'make' invocations
with the $MAKE variable to be consistent within the script.

Usefull if building for sparc64 userland, because the

making it impossible to always select the correct userland

Example usage:

and fallback to let deb-gencontrol use the host's userspace arch.

Now that we run scripts/setlocalversion during every build, it makes
sense to move all the localversion logic there. This cleans up the
toplevel Makefile and also makes sure that the script is called only
once in 'make prepare' (previously, it would be called every time due to
a variable expansion in an ifneq statement). No user-visible change is
intended, unless one runs the setlocalversion script directly.

Running "make deb-pkg" requires setting KBUILD_PKG_ROOTCMD or
becoming root oneself or it errors out.  Unless already running
as root or KBUILD_PKG_ROOTCMD is already set, use fakeroot as a
good default.

With this patch applied, you can run "make oldconfig deb-pkg" as
an ordinary user to build a binary package for an updated kernel
tree and it should just work.

fakeroot is too zealous by default in treating files as owned by
root.  Its wrapped stat() sets st_uid and st_gid to 0 for all
files, which causes Git to go on a wild goose chase if
CONFIG_LOCALVERSION_AUTO is set, checking if any file's content
has changed along with its stat information.  Avoid this by
telling fakeroot to use the actual owner and group for
preexisting files, by passing it the -u option.

Let the deb-pkg target acquire (fake) root privileges before
running commands that need them.  Without such privileges,
deb-pkg errors out because chown fails.

The new KBUILD_PKG_ROOTCMD variable, if defined, is used as a
command to run other commands with possibly fake elevated
privileges.  Since this is not needed for the tar-pkg and rpm-pkg
targets, it is only used by deb-pkg.  If it is not defined, the
behavior is as before, and the user will have to rerun make as
root.

In other words, as a shortcut, instead of running 'make oldconfig &&
make && fakeroot -u make deb-pkg', one can use the single command
'make oldconfig deb-pkg KBUILD_PKG_ROOTCMD="fakeroot -u"'.

Use the --owner= and --group= options to make sure the entries in
the built tar file are owned by root.  Without this change, a
careless sysadmin using the tar-pkg target can easily end up
installing a kernel that is writable by the unprivileged user
account used to build the kernel.

Test that these options are understood before using them so that
non-GNU versions of tar can still be used if the operator is
appropriately cautious.

For the rpm-pkg target (source + binary RPM), building with

that KBUILD_OUTPUT is not set in that case to avoid later errors.
