These are what are known as 'dangling bbappends', that is bbappends
for which there is no associated .bb. This happens for example when a
newer version of recipe is changed in one layer and we have yet to
make the associated change in meta-virt. Another case may be that we
have bbappends for recipes files which are only present when
additional layers are built. In most cases these are annoying and only
slightly concerning and thus we usually treat them as warmings and not
errors.

To make these errors become warnings set the following in your
local.conf or if you are building up your own custom layer you can
similarly do this in your layer.conf.

BB_DANGLINGAPPENDS_WARNONLY ?= "true"

Over time we usually apply updates to correct these, for example the
rpm_5 one should be corrected sometime in the near future, similarly
the kernel 4.8 one. Usually however expect some of these, be aware of
them, but don't make it stop your build.
