    kbuild: tar-pkg with out-out-tree building
    
    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.
