Bug#862756: gcc-7 cross compiler build: generated dependencies on multilib libcs unsatisfiable

[Matthias Klose]

Control: tags -1 unreproducible
Control: severity -1 normal

as talked on irc, this is not reproducible for me.  The gcc-7-cross package has
some mangling on it's own, but I don't this done for changing package
dependencies. The packages in the archive also look ok.
