So I experimented a bit more and found a minimal set of steps to reproduce the problem. Maybe that might give someone a clue as to what is happening and/or how to resolve it.

Steps to reproduce:

- clone Poky repository, checkout branch 'fido'
- go to meta-yocto-bsp/conf/machine and copy beaglebone.conf to another file (I used astro.conf)
- from poky repository do source oe-init-build-env into new build directory
- edit conf/local.conf to set MACHINE ?= "astro" (use filename from second step) and DL_DIR (if present)
- run bitbake core-image-minimal

-> kernel-abiversion is missing, build fails

- edit conf/local.conf, set MACHINE ?= "beaglebone"
- run bitbake core-image-minimal

-> image builds fine

It stays the same if the copied config is in a custom BSP layer, some minor modifications are made, etc., but to eliminate complexity I just put that into the meta-yocto-bsp layer. What strikes me as really odd is that now the only thing changed between working and non-working configuration seems to be the filename of the machine configuration - what am I missing?

How do I create a working machine configuration for Poky 1.8? (In 1.7.1 I just took some machine configuration from eldk, fiddled around with it a bit, put it into my BSP layer and never had any trouble with that.)
