v8:
-* clean up dh's handling of options passed onto commands it calls,
- by implementing one of the changes discussed in #570039
- (either change #3, change #4, or change #5; change #0 was done, but
- was an incomplete workaround)
- My preference ATM is #3, require dh options come before --,
- and after, options to be passed on to commands.
* better package arch filtering for -N , -p (#576990)
* Support DEB_BUILD_OPTIONS=debug ; maybe also support passing
-g -O2 by default. See patch (and discussion of why this breaks
compatability) in #544844.
+* Reorder build systems list. perl_build before perl_makemaker.
+ Any other changes? #578805
