Bug#707813: libc6/debconf: circular predependency hell

[Bill Allombert <ballombe@debian.org>]

Package: libc6
Version: 1.5.50
Severity: important

Hello libc6 maintainers,

There is a circular Pre-Depends loop between debconf, dpkg, libbz2-1.0, libc6,
libgcc1, liblzma5, libpcre3, libselinux1, multiarch-support, perl-base, tar and
zlib1g:

One is due to the dependency on debconf and the other on libgcc1.

debconf 	:Pre-Depends: perl-base (>= 5.6.1-4)
dpkg 	        :Pre-Depends: libbz2-1.0, libc6 (>= 2.11), liblzma5 (>= 5.1.1alpha+20120614), libselinux1 (>= 1.32), zlib1g (>= 1:1.1.4), tar (>= 1.23)
libbz2-1.0 	:Depends: libc6 (>= 2.4)
libbz2-1.0 	:Pre-Depends: multiarch-support
libc6 	:Depends: debconf (>= 0.5), libgcc1
libgcc1 	:Depends: libc6 (>= 2.14)
libgcc1 	:Pre-Depends: multiarch-support
liblzma5 	:Depends: libc6 (>= 2.4)
liblzma5 	:Pre-Depends: multiarch-support
libpcre3 	:Depends: libc6 (>= 2.3)
libpcre3 	:Pre-Depends: multiarch-support
libselinux1 	:Depends: libc6 (>= 2.14), libpcre3 (>= 8.10)
libselinux1 	:Pre-Depends: multiarch-support
multiarch-support 	:Depends: libc6 (>= 2.3.6-2)
perl-base 	:Pre-Depends: libc6 (>= 2.11), dpkg (>= 1.14.20)
tar 	:Pre-Depends: libc6 (>= 2.8)
zlib1g 	:Depends: libc6 (>= 2.4)
zlib1g 	:Pre-Depends: multiarch-support
