sbuild fails to install :native dependency

[Michał Sawicz]

To deal with bug #1353855 temporarily, we added :native to the g++-4.9 Build-Depends to some projects. Apparently sbuild has trouble with getting this installed:

The following packages have unmet dependencies:
 sbuild-build-depends-unity8-dummy : Depends: g++-4.9:native but it is not installable
E: Unable to correct problems, you have held broken packages.

Full build log attached.

Maybe the more interesting bit in the log:

sbuild: warning: can't parse dependency g++-4.9:native
