The source tree can contain lots of uninteresting data like tag or
cscope files, packaging which slows down make rpm needlessly. It can
also break the build, if the tree contains an unrelated file named
*.spec. The downside of this change is that new subdirectories have to
be added to the KBUILD_ALLDIRS variable in the top-level Makefile. The
upside is that the behavior is more predictable.

When dealing with multiple sub-arches (like 32- and 64-bit on x86, for
example) generating a bunch of kernel tar archives with the same name
but for different sub-arches could get confusing and error-prone. Also,
the build process could overwrite otherwise unrelated builds and you
probably don't want that. So, add the architecture to the archive name
for more clarity and less shoot-yourself-in-the-foot practices.

'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is
read-only.  Specifically, when the RPM spec generated by
scripts/package/mkspec is run, KBUILD_SRC happens to be set to the
source location and thus the invocation of 'make headers_install'
fails when an internal call to 'filechk' tries to write a file into
the source tree.

The fix is to clear KBUILD_SRC for the 'make headers_install'
invocation in the spec file, as is already done for the 'make
modules_install' invocation.

For large kernel configurations (like a distribution kernel)
targz-pkg takes a quite long time to just do the compression.
I clocked it at 15+mins for a SUSE kernel like config on a fast
system.  And tarxz and bzip2 are even slower.

The main reason is that the script that is doing the taring sets
the highest compression level (-9).  When I change it to just
use the defaults the gzip time for the same kernel goes down
to ~3 mins. I haven't tested xz and bzip, but I expect those
to be much faster too.

I'm not willing to wait that long for a small compression
gain. So just change the script to use the defaults.

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.
