“Is this a new error ? i.e. it used to work ?”
Yes, this, I believe, used to work with poky/jethro.   I will double check.

We fixed this on master (but on master, we thought it was due to my recent kernel tools
changes), but this makes me think it is a delta in the QA checks as well .. which may
have been backported to kergoth.
Is this a new error ? i.e. it used to work ?
The issue is that x86 defaults to 64bit, and this is a 32 bit build. We had to force disable
it, to get the kernel to build 32bit.
The commit is here (on git://git.yoctoproject.org/yocto-kernel-cache<https://urldefense.proofpoint.com/v2/url?u=http-3A__git.yoctoproject.org_yocto-2Dkernel-2Dcache&d=DQMFaQ&c=oTZJxWjXA97U5efbDJZGEg&r=uNDdMisgO1TeK0HLqspkDVxt_f3Oh6mt6bTm6TDLFdI&m=q3FIpi-36wdwCMxTRpfRClrAEYMkL_twst0DqByf4BE&s=oSobJkqMs6iTwF6TosJ3WIabToWCvoEokuxrRG6FkZA&e=> yocto-4.4 branch):

    common-pc: enforce 32 bit

    ARCH=x86 defaults to 64 bit on modern kernels. So we need to
    explicitly disable 64bit in common-pc if we want a 32bit build
    (common-pc builds with ARCH=x86, not ARCH=i386)

And I'd bet that isn't in play on krogoth, since unless my -stable kernels have come back,
the kernel-cache update wouldn't have either.

My local.conf contains the following 2 lines:

PREFERRED_PROVIDER_virtual/kernel = “linux-yocto-rt”
COMPATIBLE_MACHINE_genericx86 = “genericx86”
