Reading through dh_strip since we have no old -dbg package to care about it might be enough to just do:

export EXTRA_CFLAGS = -g

- the export makes sure we build it for all binaries
- dh_strip magically does the right thing and should create a dbgsym packages as appropriate

This bug was fixed in the package dpdk - 2.2.0-0ubuntu6

---------------
dpdk (2.2.0-0ubuntu6) xenial; urgency=medium

  * d/dpdk-init fix handling of multiple huge page sizes (LP: #1557532):
     - dpdk-init now ensures non-default-hugepage-size mountpoints are
       available as well.
     - extra mountpoints are only created if requested in dpdk.conf and not yet
       available (e.g. by the admin).

     - dpdk-init no more checks /sys/.../driver of the device unconditionally
     - removed the superfluous tr call in that path
