Hi Mart,

If you create an overlay, you can fairly easily tweak individual .bb files 
to strip them down without rewriting the entire recipe.

You can list your overlay dir before the OE recipe dir in COLLECTIONS. Set 
FILESPATHBASE to look in your COLLECTIONS for extra patches and files, 
include amend-recipes.inc from your distro conf, and create amend.inc in 
your overlay for any recipes you want to mangle.

This is what the COLLECTIONS and FILESPATHBASE setting looks like:

amend-recipes.inc:

An amended recipe:

(Don't expect much in that repo to work...)
