Thomas, All,

On 2017-12-01 21:53 +0100, Thomas Petazzoni spake thusly:
> This commit moves the host-fakedate dependency handling from
> DEPENDENCIES_HOST_PREREQ to a proper regular dependency handled by the
> package infrastructure.
> 
> host-fakedate is added as dependency to all packages, except
> host-skeleton, because we depend on it.
> 
> In addition, we make sure that host-fakedate does not grow a
> dependency on host-{tar,xz,lzip,ccache} to avoid circular
> dependencies. host-fakedate does not need any extraction tool and does
> not need to build C/C++ code (the source code is just a shell script
> available in Buildroot).

Those last three conditions are using the exact same list, maybe we can
re-factorise the code to avoid duplicating that list?
