Bug#837198: fwupdate not buildable on armhf and arm64, unsatisifiable build-dependency.
fwupdate cannot be built on armhf and arm64 due to a build-depends on
libsmbios-dev which is only available on i386 and amd64. It has
previously build on these architectures so this needs to be dealt with.
In general for problems like this there are three possible soloutions in
descending order of preference.
1. Make the build-dependency available.
2. Disable features on the affected architectures and add an
architecture specification to the build-dependency.
3. Request removal of the outdated binaries.
