Bug#789430: gcc-4.9-arm-linux-gnueabihf can't be installed; depends on libgcc-4.9-dev:armhf (= 4.9.2-18) but 4.9.2-21 will be installed

Package: gcc-4.9-arm-linux-gnueabihf
Severity: grave
Justification: renders package unusable

Dear Maintainer,

When I try to install gcc-arm-linux-gnueabihf, neither apt-get, nor aptitude,
are able to do it, because gcc-4.9-arm-linux-gnueabihf depends on version
4.9.2-18 of libgcc-4.9-dev, but only 4.9.2-21 is available. The same for
gcc-4.9-arm-linux-gnueabi.

Thanks.
