This is just for the kernel issue, right?
In that case, just use ${@bb.utils.contains("TUNE_FEATURES", "mx32",
"xxxx", "" ,d)} in the kernel recipe code...
It's possible that there will be other recipes that need patches or
other changes in the future, but I guess we can cross that bridge when
we come to it.
I think I will actually use the features update that Bruce just added
from here instead. Since multiple BSP could take advantage of x32 we
should not have to edit each of there kernel recipes. It should just be
enabled based on the x32 DEFAULTTUNE.
I know there are a few other things that can (and should) change behavior based
on the x32 flag.. but flag or override, it just changes slightly the
implementation mechanism -- either should work as long as we consistently use it.

Thanks
Sau!
