Setting BBFILE_PRIORITY allows you to prioritize a
layer against other layers that contain the same package - effectively
letting you control the precedence for the multiple layers.
The precedence established through this variable stands regardless of a
layer's package version (PV variable).
For example, a layer that has a package with a higher PV value but for
which the BBFILE_PRIORITY is set to have a lower precedence still has a
lower precedence.</para>
<para>A larger value for the BBFILE_PRIORITY variable results in a higher
precedence.
For example, the value 6 has a higher precedence than the
value 5.
By default, the BBFILE_PRIORITY variable is set to the value 5.</para>
