Thanks for your bug reports and patches!

While I like to support improving crossbuildability, I have the
impression that the issue you address in these 2 patches affects
hundreds of packages, and that adding boilerplate code to all
debian/rules files is the wrong approach (and doesn't scale). I guess
this needs to be tackled at a deeper level, probably the two perl
buildsystems in debhelper.

Incidentally, Niko look at crossbuilding arch:any perl packages at
our recent sprint briefly. What I find in our gobby notes is

| implement debhelper support for cross building XS module packages?
| 	effectively make debhelper run 'perl -I /usr/lib/<arch>/perl/cross-config-5.28.1 Makefile.PL' when it detects a cross build

which points in the same direction. And I'm sure Niko can add more on
this topic than I :)


Cheers,
gregor
