It shouldn't though, since the application of the meta-tlk SRC_URI
bbappend should follow the SRC_URI assignment in the cedartrail
bbappend.  On the other hand, the layer priorities don't seem to be
right - meta-cedartrail is supposed to have a priority of 6, but it
doesn't actually seem to:

BBFILE_PRIORITY_cedartrail = "6" 

[trz at empanada build]$ bitbake-layers show_layers
layer                 path                                      priority
==========================================================================
meta                  /home/trz/yocto/crownbay-test/meta        5
meta-yocto            /home/trz/yocto/crownbay-test/meta-yocto  5
meta-yocto-bsp        /home/trz/yocto/crownbay-test/meta-yocto-bsp  5
meta-intel            /home/trz/yocto/crownbay-test/meta-intel  5
meta-cedartrail       /home/trz/yocto/crownbay-test/meta-intel/meta-cedartrail  5
meta-tlk              /home/trz/yocto/crownbay-test/meta-intel/meta-tlk  5

On the other hand, meta-tlk does follow meta-cedatrail in the parse
order so should append to the SRC_URI...
