[OE-core] still seems to be a pile of "_append +=" stuff in oe-core

[Robert Yang]

The _append and += are different, so we need either:

var_append = " foo"
or
var_append += "foo"

for example:

var += "foo"
var = "A"

Then var will be "A".

But:
var_append += "foo"
var = "A"

Then var will be "A foo"
