I think I found it.

The image installs the dropbear SSH server, and the openssh-sftp-server. These 
seem to cause a conflict, and then ALL the "-dev" packages get skipped.

The warning looks like this (I removed some sensitive information and a list 
of a few hundred package names):


WARNING: prolira-delirium-image-1.0-r0 do_populate_sdk: Unable to install

If I remove "openssh-sftp-server" from the packages, the warning (which should 
have been an error?) disappears and the resulting SDK properly contains all 
the pkg-config files again.

I wonder if there's a proper fix to prevent this, i.e. break the link between 
openssh-sftp-server and openssh-dev.
