Please explain which toolchain you are yusing, which  libraries,  and
which versions of the tools listed above.

Where did you get these object files from?

I have a suspicion that these are  in  fact  parets  of  the  busybox
toolbox.  If  this  is  correct,  then  why  don't you simply use the
Makefile that comes with busybox?

You can strip the shared libraries for the target.

Again, I have the suspicion  that  this  code  comes  from  our  SELF
package.  The  scripts provided by SELF take care of all the problems
you are running in.

No, this will most probably just increasy your memory footprint.

What I don't understand: there is a working set of tools and scripts.
You rip it apart, omit essential parts, and then complain that it  is
not working any more.

What else did you expect?
