It's possible that you are using (or might use) different layer

One build might have a bbappend file that another build doesn't need.
Yes, you are right. I use different conf/bblayers.conf for different
SOC. But within the same SOC's different output
(board image, SDK), I just change MACHINE and SDKMACHINE. Is it safe
to build all outputs of the same SOC
in one build dir?
Yes.
Also, different builds may have different DISTRO_FEATURES.
Thus, having different deploy directories is better. Otherwise,
your package feeds might be broken. And you would suffer trying to
maintain it.
You mean I can't build two output with different DISTRO_FEATURES in
the same build dir.
Any other config var? What about MACHINE and SDKMACHINE?
Yocto doesn't ensure that changing distro features in the same build
directory works.
It might work, but it's also possible that it doesn't.
Changing MACHINE and SDKMACHINE is OK.
