can you be a bit more specific? not sure i understand completely what
you want to do. also how are you getting your distribution? it's
prebuilt and you only have the image or you build it yourself from
recipes?

telling us more about the trouble might be useful. also telling how
you build the toolchain and sysrootfs.

well, that would definitely be the more natural way of customizing
existing recipes. that's what most people would do in their own
layers, generally with .bbappend recipes. it's probably even easier to
do that building your own toolchain/SDK to some extends.. why don't
you like this option?
