Bug#626094: perl: debian/patches/fixes/processPL.diff is obsolete

[Niko Tyni]

Package: perl
Version: 5.12.3-6

We've been carrying the fixes/processPL divergence to ExtUtils::MakeMaker
for five years because of #357264.

I finally looked into this; the issue was a change in EU::MM 6.30
(shipped with Perl 5.8.8) that made the pdl package FTBFS.

The upstream ticket [rt.cpan.org #17224] is rather confused and got
closed with no changes.

I think the problem was fixed for pdl 2.4.3 shortly afterwards with commit

 http://pdl.git.sourceforge.net/git/gitweb.cgi?p=pdl/pdl;a=commitdiff;h=a8849de2ca393fd308c9cfcea6d626b37d9d8728

I've verified that

- pdl does    build                              with    our divergence (obviously :)
- pdl does    build                              without our divergence
- pdl doesn't build if the above fix is reverted without our divergence (#357264)
- pdl does    build if the above fix is reverted with    our divergence

At some point I think we should revert the patch, possibly with some test
rebuilds first to make sure no other package in the archive is relying
on our divergence. (IMO this is a bit overly defensive but easy enough
that it may be worth doing.)
