The configured you have is correct to build the linux-yocto_3.19
kernel. Without seeing the error output I can only guess as to the
error you are seeing.

It is likely to be the error that refers to shared install files being
provided by two sources
(https://github.com/openembedded/openembedded-core/blob/master/meta/classes/sstate.bbclass#L198).
If that is the message you are seeing the simplest way to resolve it
is to delete your 'tmp' directory and rebuild your image (which will
be quick as it will populate from shared state cache). This occurs
because you have built the linux-xlnx kernel first.
