[OE-core] [PATCH] Introduce IMAGE_LINGUAS_COMPLEMENTARY

[Andreas Müller]

The allows layers adding packages other than locales automatically to images
according to what user selects in IMAGE_LINGUAS.

E.g if a layer has recipes creating packages as:
| ${PN}-foo-en-us / ${PN}-foo-en-gb / ${PN}-foo-de / ..

it would set
| IMAGE_LINGUAS_COMPLEMENTARY_append = " *-foo-%s"

in layer.conf to make those packages matching IMAGE_LINGUAS added to image.
