All the busybox builds I did for the past 3 (maybe 4) years have been EABI. People tracking a git kernel should just "get with the program" I guess :) And let's not forget that due to the ABI differences things like alsa don't work properly with EABI kernel + OABI rootfs.
Enabling the OABI compat also introduces a bit of overhead when used with a pure EABI rootfs.
