Bug#1021506: binutils-common: not co-installable due to differing content of /usr/share/man/man1/ld.gold.1.gz

[Johannes Schauer Marin Rodrigues]

Package: binutils-common
Version: 2.39-4
Severity: important

Hi,

in src:2.39-4, a Build-Depends on help2man was added. This enabled the
codepath checking "which help2man" in d/rules which leads to man pages
generated for ld.gold by help2man. These man pages differ for different
architectures and thus, binutils-common becomes uninstallable with
itself. Steps to reproduce:

$ mmdebstrap --arch=amd64,arm64 --include=binutils-common:amd64,binutils-common:arm64 unstable /dev/null
[...]
Unpacking binutils-common:arm64 (2.39-6) ...
dpkg: error processing archive /tmp/apt-dpkg-install-E9IDZj/70-binutils-common_2.39-6_arm64.deb (--unpack):
trying to overwrite shared '/usr/share/man/man1/ld.gold.1.gz', which is different from other instances of package binutils-common:arm64
Errors were encountered while processing:
/tmp/apt-dpkg-install-E9IDZj/70-binutils-common_2.39-6_arm64.deb

The differing content looks like this (using amd64 and arm64 as an
example):
