* The merged contents file didn't work out, so nuke it and put it back
into each port directory. Most still have the now-pointless conditionals;
these now should be deleted.
* fix alpha, amiga, and arm32 to delete the maze of twisty little conditionals
commandlines for all tar operations. (work supplied by Matt Green)
2) Update arch/*/md.c to deal with new sysinst/run.c. Special case
anything that needs to do a redirect or a pipe.
3) #if 0 some unused code in target.c. This code will need to be updated,
or special cased with do_system.
Big thank you to Matt for all his work on this.
have time to make the install tools handle release.7 layout.
Restore the change mycroft made in revision 1.3 (accidently
removed in my previous commit). Update sizes again.
