Because libperl is built as PIC code, which would be substantial overhead
for the perl interpreter on i386.

In my opinion, this shouldn't be a sufficient rationale to block getting
perl DSOs linked right, but then I have rather strong opinions about DSOs
and have to regard myself as biased. :)

Even if i386 doesn't start linking to libperl, it seems to me that the
MakeMaker change should be doable on a per-arch basis (though preferably
without having to move perl-modules from Arch: all to Arch: any).
