Subject: [PATCH] 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 DEBARCH=i386 deb-pkg

This patch is based on my 'kbuild, deb-pkg: select
userland architecture based on UTS_MACHINE' patch.
