Hi, thanks for the report. I'm happy if the cross build hack in src:perl
is useful but I'm not quite sure what to do about this.

Eyeballing the patch, I think that cross building with this config would
result in a broken package due to at least missing -DDEBIAN in ccflags.
Also, -DAPPLLIB_EXP="/usr/lib/aarch64-linux-gnu/perl-base" looks wrong,
and possibly breaks the perl-base package when used without perl et al.
I doubt these are the only problems.

I assume "tested in rebootstrap build" means the package builds, but
did anybody test the resulting packages?

I'm copying Helmut. Do you have any suggestions? Should I just take this
in and leave it to porters to worry about breakage?

BTW, our development is currently targeting 5.34 so somebody needs to
port this. I'm not sure if there will be another 5.32 upload before
we get 5.34 in unstable.
