Digging into this has uncovered a small rat's nest of problems! There 
are a around 25 recipes that use binconfig and most of them deliver just 
libraries and a -config command.  There are a number of cases where more 
content is delivered in the FILES_${PN}.

Using the buildhistory tools I was able to see that there are more than 
just pcap with this issue, and moving to the code below does not seem to 
work correctly, since it places the -configs into 
<some_path>/tmp/sysroots/${MACHINE}/<some_path>/tmp/sysroots/${MACHINE>, 
because ${STAGING_BINDIR_CROS} contains  ${STAGING_DIR_HOST} already!

And it's not clear that the FILES_${PN}-dev addition does the correct 
thing since FILES_${PN} is greedy in $bindir, another set change would 
be required to exclude the *-config files from FILES_${PN} which 
currently most of the recipes do by overriding FILES_${PN} with just the 
*.so* line, except for the ones like cups which has a huge amount of 
FILES_${PN} delivered.

I am digging!

Sau!
