Hmm.  Can you rerun the test, with the 'set +x' removed that I asked you
to add?  Probably a good idea to gzip the output to not exceed
bug-libtool list size limits.

Normally to bash.  For doing the test, however, I did this:
Let /bin/sh point to dash.  Start zsh, export SHELL=/bin/zsh, unset
CONFIG_SHELL, run ../libtool/configure.

My trace output looks very much like yours, AFAICS.
