[OE-core] How to find out why shared sstate is not being used for a recipe

[Mike Looijmans]

I have a deja-vu feeling about this question.

I have this recipe:

https://github.com/topic-embedded-products/meta-topic/blob/master/recipes-bsp/fpga/fpga-image-miami.bb

Which includes this one:
https://github.com/topic-embedded-products/meta-topic/blob/master/recipes-bsp/fpga/fpga-image.inc

I have a build server that exports its sstate-cache directory through HTTP, 
and a local host that attempts to use that sstate-cache. This works fine, 
except for the recipe above. Building this recipe takes about 1 hour, so i 
really really really want to share that state at any cost. As you can see, 
I've done a big shotgun blast of "vardepdsexclude" to get the recipe to be as 
common as possible. Still any host wants to build its own version.

How can I diagnose the REASON that my machine thinks it isn't building the 
exact same thing as the build server?
