We experience the following error and fail to boot on qemu64 machine
/lib64/libc.so.6: CPU ISA level is lower than required
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00007f00
As stated in [1],
Passing -march= causes glibc to add annotations not compatible to run
result on -march= as too high ISA level is inferred.
ISA level is a new feature of 2.33 release.
Until it's fixed let's disable ISA level inference with
libc_cv_include_x86_isa_level=no
(no better configure option yet).

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
