Bug#1100390: libcompress-raw-bzip2-perl is wrongly marked Multi-Arch: same

[Helmut Grohne]

Package: libcompress-raw-bzip2-perl
Version: 2.213-1+b1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: fileconflict

libcompress-raw-bzip2-perl is marked Multi-Arch: same, but
/usr/share/man/man3/Compress::Raw::Bzip2.3pm.gz actually differs between
amd64/arm64/i386 and armel/armhf/mips64el/ppc64el/s390x. As a result
unpacking multiple instances fails:

Errors were encountered while processing:
 libcompress-raw-bzip2-perl_2.213-1+b1_ppc64el.deb

On the flip side, using Multi-Arch: same doesn't practically work,
because it depends on perl-base, which is not coinstallable. As a
result, I recommend dropping it.
