create tar file with target name as base and include bit file

[pwittich]

Propose to change the tar file that gets created from the top level being "address_table, bit, ..." to NAME/address_table, etc, where NAME is the makefile target that was called in the original make invocation. can easily be done by something like

tar --transform 's,^,'%',' ...

this would allow these files to be untarred directly in /fw/CM without needing to make the parent directory.
