Bug#1044137: libc++1-16 is not actually co-installable

[Samuel Thibault]

Package: libc++1-16
Version: 1:16.0.6-10
Severity: normal

Hello,

Trying to run:

apt install libc++-16-dev:amd64 libc++-16-dev:i386

I get:

These packages are marked Multi-Arch: same, but they are not actually
co-installable.
