As far as I can see, those symbols appear if and only if you alter
the configure invocation to add --enable-debug. cdbs does this
automatically if you build with DEB_BUILD_OPTIONS=debug - is that
what you were doing?

The requirement that Debian packages must build from source is only
release-critical for the configuration that actually gets released,
which has no special DEB_BUILD_OPTIONS, so I'm downgrading this to
a normal bug.

(The right solution is probably to conditionalize the -c4 in
DEB_DH_MAKESHLIBS_ARGS so it is only used if DEB_BUILD_OPTIONS
does not contain debug.)
