Update: this formulation avoids an unnecessary patch to the perl package
until the ABI is actually changed. It also allows debhelper and the
few other affected packages to easily stay compatible with older perl
package versions.

I'm thinking the dependants could use something like
 "perlapi-" . ($Config{debian_abi} || $Config{version})
