Bug#841923: AW: AW: Bug#841923: libclang-common-3.9-dev: missing multilib binaries

[Sylvestre Ledru]

I wonder if we should not move the new files into a dedicated packages.

When installing this package, it is installing new packages (lib32gcc1, 
lib32stdc++6 and libc6-i386) [1]
This would increase the installation size quite consequently for a 
specific case.

What do you think?

Thanks
S

Unpacking libclang-common-3.8-dev (1:3.8.1-13) over (1:3.8.1-13) ...
dpkg: dependency problems prevent configuration of libclang-common-3.8-dev:
  libclang-common-3.8-dev depends on lib32gcc1 (>= 1:3.3); however:
   Package lib32gcc1 is not installed.
  libclang-common-3.8-dev depends on lib32stdc++6 (>= 4.1.1); however:
   Package lib32stdc++6 is not installed.
  libclang-common-3.8-dev depends on libc6-i386 (>= 2.2.4); however:
   Package libc6-i386 is not installed.
