Merge branch 'packaging' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6

* 'packaging' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild-2.6:
  deb-pkg: s/hdr/kernel_headers_/ && s/header/libc_headers_/
  deb-pkg: Make deb-pkg generate a seperate linux-libc-dev deb
  kbuild: create linux-headers package in deb-pkg
  kbuild, deb-pkg: support overriding userland architecture
  kbuild, deb-pkg: select userland architecture based on UTS_MACHINE
  kbuild, deb-pkg: Fix build with paranoid umask

The output directory can also be specified using "O=...".
Setting "O=..." takes precedence over KBUILD_OUTPUT.
KBUILD_DEBARCH
--------------------------------------------------
For the deb-pkg target, allows overriding the normal heuristics deployed by
deb-pkg. Normally deb-pkg attempts to guess the right architecture based on
the UTS_MACHINE variable, and on some architectures also the kernel config.
The value of KBUILD_DEBARCH is assumed (not checked) to be a valid Debian
architecture.
ARCH
--------------------------------------------------
Set ARCH to the architecture to be built.
