Poky has two:
   meta/conf/abi_version.conf
   meta-yocto/conf/abi_version.conf
and they are different:
   $ diff -u meta/conf/abi_version.conf meta-yocto/conf/abi_version.conf
   --- meta/conf/abi_version.conf  2012-03-16 05:28:23.000000000 -0600
   +++ meta-yocto/conf/abi_version.conf    2012-03-16 05:28:23.000000000 -0600

   -OELAYOUT_ABI = "7"
   +OELAYOUT_ABI = "8"

So, as Robert Day pointed out, depending on how these layers are
processed, you get different build results...
