Yes, I must admit the symbols soup does not make this structure
very apparent.  I modified the patch and tried to adapt the
logic here without drifting too much out of the original file,
yet it required reorganizing the commands a bit.  After some
testing, error codes from the linking stage should be returned
properly; if otherwise then I would tend to think the linker
didn't return an error code in the first place.

Agreed.  I did a thorough rereading of the Makefiles, and got
rid of the "@" prefix of most commands.  Build logs are now
showing what is happening, so even if changes here over are not
sufficient to close the bug yet, at least the verbosity level
should now allow to see more clearly what is happening.

I made the patch available on Salsa.  If maybe you wish to have
a try and review changes, before further package upload, you can
grab it here:


I hope this one will help.
