Outside of the normal patch refreshes and boot issues, there are

For ORC_UNWINDER support in x86-64:
DEPENDS += "${@bb.utils.contains('ARCH', 'x86', 'elfutils-
native elfutils', '', d)}"
do we need both target and host elfutils
Yup. There were references to both. Some had to run for hostcc
and others in the target arch.
Just for reference this is pretty bad for performance as it delays the
kernel compile until some substantial parts of userspace build.
Is ORC_UNWINDER useful and commonly used?
One other thought I had was that this could be a distro feature
toggle, versus an arch feature. i.e. if you want the more
accurate stack unwinding in a debug build.
