[yocto] SDK: getting error "xmlcatalog: not found" installing SDK

[baisch at tau-tec.com]

Hello everyone,

I was able to workaround this issue: 

In `conf/bblayers.conf` I put my custom layer ontop of the `meta` layer. Since classes seem to ignore the priority set by the layer config. Then I copied the `classes/xmlcatalog.bbclass` class to my layer and in the file I changed `xmlcatalog` to `${bindir}/xmlcatalog`.

I'm still not sure if this an error specific to my setup or a general issue which should be fixed. Also I was hoping there is a better solution since changes to the original `classes/xmlcatalog.bbclass` will always be overridden.

Regards,

- Michael
