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
