I can't use '+=' in my conf/local.conf because '=' on the recipe has
precedence.
I also can't use the 'append' because it doesn't work with flags.

I guess I only have the chance to use os-release.bbappend left.
However, to maintain the layer YP compatible, I need to use an override,
and this implies the use of another variable.

MY_BUILD_ID = "my-build-id"

MY_BUILD_ID_AUX:override = "${MY_BUILD_ID}"
BUILD_ID = "${MY_BUILD_ID_AUX}"
BUILD_ID[vardepsexclude] += "MY_BUILD_ID_AUX"

However, I didn't want to have this in a bbappend because it's not very
elegant
and this is mostly meant to be used only in CI.

There might be another way to do this, but I don't see how without using
the weak assignment.

Thanks

Jose
