The command line that causes this is:

This is trying to build a shared library with -pie, which is not going 
to fly. -pie (and -fPIE) is only for executables.

Now, I don't see any mention of pie in debian/rules, or in the old build 
log, so I guess this flag must have come from a (broken) library.
