[Bug other/33087] Add dependency information to object files and make use of it

[pinskia at gcc dot gnu dot org]

You can use ccache to get this same behavior.  You can also use -MD to get
automatic dependency checking.

>ideally including the checksums of the source files used to build it

That will not work for some stuff where headers change.  You are better off
using ccache which is actually a nice addon program that is already done to
deal with this use case really.
