Hmm, ok.  Can you show a bit what you're doing?  My small tests with
libtool/tests/demo must be too simplistic to expose the issue fully.

Meanwhile, I think there also is a simple workaround: if you configure
with an absolute path:
  mkdir build
  cd build
  /absolute/path/to/source/tree/configure [...]
  make

then you should be able to skip the symlinking step; but it seems you
still have to go to the .libs subdirectory.  Not yet sure how to go
about a better solution.

Cheers,
Ralf
