It appears that libdbi-perl is included in the list for the ldbl transition
because of the file /usr/lib/perl5/auto/DBI/dbipport.h.  I don't believe
that anything in Debian builds against this file, but then I also don't know
why it's in the package at all.  If other packages do build against this
header, then there is at least potentially an ABI change that needs to be
handled.  If this header is dead weight, then no changes need to be made to
the libdbi-perl package for this bug report (not even "depending on a perl
that is compiled with the new glibc/gcc").
