I'll try to track that version down.

Isn't newlib_basedir set to the top level of newlib by every package?
It sure seems like that is what is going on in all of the sub-configures.

If so, then this:

  abs_newlib_basedir=`cd ${newlib_basedir} && pwd`

should always equate to the same thing no matter where it's run.  In
the subjdirectories, it will just get rid of trailing ..'s which bring
you back to the top.
