kbuild, deb-pkg: support overriding userland architecture

Usefull if building for sparc64 userland, because the
sparc and sparc64 userlands use the same 64-bit kernel,
making it impossible to always select the correct userland
architecture for the resulting debian package.

Might also be usefull, if you want a i386 userland with a amd64 kernel.

Example usage:
	make KBUILD_DEBARCH=i386 deb-pkg

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.
