If you have .bbappend file(s) but no .bb files in your layer you would expect 
that message, it's telling you one of the entries in BBFILES is not matching. 
There are several options here:

1) You can ignore the warning (it's just a warning)

2) Remove the .bb entry from BBFILES in meta-saxo/conf/layer.conf (you can add 
it back if and when you need it - of course that does mean you could forget to 
do that and then wonder why adding a .bb file doesn't work)

3) Set BBFILE_PATTERN_IGNORE_EMPTY_saxo = "1" to disable the warning.

Cheers,
Paul
