Thank you Ian, Cayetano for swiftly reminding me to Read The Manual.  I was so 
tired with constant tweaking of package after package, that I forgot to go to 
the basics.

I learned that I can source variables to emulate the build environment, in 
which I issued the same command that go build system uses to build the 
package.  Here is the result, much cleaner with the interesting stuff right at 
the end:

I remember faking a Proton’s fork with the upstream package because GitHub 
failed to find it.  It could be the one, or not.  At least I have a thread to 
follow now; and a new tool for deep inspection.
