After thinking it over, I think now would be a good time to move
/usr/lib/perl5 and /usr/lib/perl/<VERSION> to the multiarch paths
(/usr/lib/<triplet>/perl5 and /usr/lib/<triplet>/perl/<VERSION>. 

This is a necessary precondition for future Multi-Arch:same packages but
can be done in advance. It's easiest to do with an ABI change, when all
the XS modules need to be rebuilt anyway.

Packages should generally do the right thing, as long as they use
$Config{archlib} and $Config{vendorarch}, which well behaved packages do.
Still, this needs a Perl policy change.

I've pushed preliminary 5.19.11 packaging to our Alioth repository
as ntyni/debian-5.19. I haven't tagged it as those are pretty much
irrevocable, but f8ec2d0ebcf73f2bf19ccc15167bb70c18a56228 is the commit
I pushed. The last two commits are the multiarch related ones.

I suppose the next step should be some test rebuilds to get an idea of
the fallout. Ideally  one set of rebuilds with the multiarch commits
and one without them.

My first few smoke tests showed that liblocale-gettext-perl builds
successfully, but eperl and epic4 break do to the /usr/lib/perl ->
/usr/lib/<triplet> change, the latter silently by failing to detect
libperl and building without. OTOH, epic5 seems to work fine.
