the issue is caused by underlinked libraries in simgear, but it is hard to fix due to circular dependencies.
patch disabling --as-needed for a single library available in debian bug

Hi Julian,

I'd like to upload the fix to Ubuntu and sync back the package when the final fix is applied to the simgear package, so If you are willing to prepare a debdiff for the package in Ubuntu, I'll be happy to upload it. If you're not, I'll take your patch (giving you the credit, obviously) and create the corresponding revision of the package.

thanks!

This bug was fixed in the package flightgear - 2.0.0-4ubuntu1

---------------
flightgear (2.0.0-4ubuntu1) oneiric; urgency=low

  [ Julian Taylor ]
  * utils/propmerge/Makefile.in: patch to unconditionaly link with sgmisc with
    --no-as-needed. This fixes a FTBFS because of missing symbols (LP: #749249)

  * Rebuilt also fixes LP: #827667

  [ Fabrice Coutadeur ]
  * debian/rules: copy config.guess and config.sub in configure-stamp instead of
    clean target to keep the diff as small as possible
