[yocto] is it "IMAGE_INSTALL +=" or "IMAGE_INSTALL_append ="?

IIRC, the evaluation orders is:

1. variables on the command line (e.g., 'MACHINE=beagleboard bitbake
myimage') are evaluated first,

2. variables in local.conf,

3. Rest depends on the order of things in bblayers.conf *and* how any
given layer.conf is implemented (some layers preppend their stuff to the
BBPATH and some layers append; from memory the Yocto layers prepend, but
layers from OE usually append, and this inconsistency makes for lot of
fun when combining layers into custom distro).
