Bug#714504: cannot upgrade to 4.8.1-5 on multiarch (amd64 and i386)

[Giuseppe Bilotta <giuseppe.bilotta@gmail.com>]

Package: gcc-4.8
Version: 4.8.1-4
Severity: serious

gcc-4.8 and related packages are at different versions in sid on amd64
(4.8.1-5) and i386 (4.8.1-4), but the same version _must_ be installed
for all architectures. This prevents upgrading of gcc-4.8 and all
related packages on multiarch (amd64 + i386) systems.
