This issue makes mips* compilation fails [1], see:
https://buildd.debian.org/status/fetch.php?pkg=vxl&arch=mips&ver=1.17.0-3&stamp=1369190209

However the compilation error does not make any sense, indeed:

$ cd obj-x86_64-linux-gnu
$ grep -r _ZN16bwm_observer_cam14backproj_pointE13vbl_smart_ptrI13vsol_point_2dERS0_I13vsol_point_3dE12vgl_plane_3dIdE
*
Binary file contrib/brl/bbas/bwm/CMakeFiles/bwm.dir/bwm_plane_fitting_lsf.o
matches
Binary file contrib/brl/bbas/bwm/CMakeFiles/bwm.dir/bwm_observer_cam.o matches
Binary file contrib/brl/bbas/bwm/CMakeFiles/CMakeRelink.dir/libbwm.so.1.17.0
matches
Binary file lib/libbwm.so.1.17.0 matches
$ nm contrib/brl/bbas/bwm/CMakeFiles/bwm.dir/bwm_observer_cam.o | grep
_ZN16bwm_observer_cam14backproj_pointE13vbl_smart_ptrI13vsol_point_2dERS0_I13vsol_point_3dE12vgl_plane_3dIdE
00000000000004f0 T
_ZN16bwm_observer_cam14backproj_pointE13vbl_smart_ptrI13vsol_point_2dERS0_I13vsol_point_3dE12vgl_plane_3dIdE


So why is is possible that symbols is not found afterward:

$ nm -D ./contrib/brl/bbas/bwm/CMakeFiles/CMakeRelink.dir/libbwm.so |
grep _ZN16bwm_observer_cam14backproj_pointE13vbl_smart_ptrI13vsol_point_2dERS0_I13vsol_point_3dE
                 U
_ZN16bwm_observer_cam14backproj_pointE13vbl_smart_ptrI13vsol_point_2dERS0_I13vsol_point_3dE12vgl_plane_3dIdE
