Bug#656739: Old gdc binaries blocking testing migration of gcc-defaults

[peter green <plugwash@p10link.net>]

Package: gcc-defaults
severity: important
version: 1.111

gcc-defaults recently switched the default gdc to gdc-4.6 and in the 
process dropped the gdc binary package on architectures that don't have 
gdc-4.6 (armel, ia64, mips, mipsel, powerpc, s390, sparc, armhf and 
s390x). This is blocking the migration of gcc-defaults to testing .

Please can you either turn this bug into a removal request for the old 
gdc binary packages or restore a gdc-4.4 based gdc package on those 
architectures.
