Commit 7e1c0477 (kbuild: Use relative path for $(objtree)) assumes that
the build process does not change its working directory. make tar-pkg
was a couterexample, fix this by changing directory only for the tar
command and not for the whole script, which at one point references the
now relative $(objtree).

A lot of 64-bit systems supported by Linux/MIPS have boot firmware or
bootloaders that only understand 32-bit ELF files, and as such, the vmlinux.32
target exists to support these systems. Therefore, it'd be nice if the tar-pkg
target recognised this, and included the right version when packaging up a
binary of the kernel.
This updates buildtar to support MIPS targets. MIPS may use 'vmlinux'
or 'vmlinux.32' depending on the target system. This uses 'vmlinux.32'
in preference to 'vmlinux' where present (although I should check which
is newer), including either file as /boot/vmlinux-${version}.

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.

Pull kbuild changes from Michal Marek:
"The main part of kbuild for v3.7 contains:
- Fix for scripts/Makefile.modpost to not choke on a '.ko' substring
in the build directory path
- Two warning fixes (modpost and main Makefile)
- __compiletime_error works also with gcc 4.3
- make tar{gz,bz2,xz}-pkg uses default compression settings instead
of saving as many bytes as possible (this should actually be in the
misc branch, I don't know why I applied it here)."
* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
compiler-gcc4.h: correct verion check for __compiletime_error
modpost: Permit .GCC.command.line sections
Kbuild: use normal compression settings for tar*-pkg
scripts/Makefile.modpost: error in finding modules from .mod files.
kbuild: Remove useless warning while appending KCFLAGS
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.

There were reports of users destroying their Fedora installs by a kernel
tarball that replaces the /lib -> /usr/lib symlink. Let's remove the
toplevel directories from the tarball to prevent this from happening.

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.

Fix out-of-tree builds for the tar-pkg targets
When I wrote the buildtar script, I didn't even think about
out-of-tree builds because I didn't use these back then. This patch
throughoutly uses ${objtree} instead of `pwd`.
Also, the kernel version is no longer manually built. Instead, it will
properly use $KERNELRELEASE . Installing modules is only done if
CONFIG_MODULES is set.

It adds tarball packaging, which I prefer for distribution.
Also one of the two blanks after @echo is removed. One seems to be enough :)
