Lili Li f8fcc057d5 kernel.bbclass: Fix Module.symvers support
Starting from v5.8-rc1 commit 269a535ca931 (modpost: generate
vmlinux.symvers and reuse it for the second modpost"), kernel will
generate new vmlinux.symvers instead of dumping all the vmlinux symbols
into Module.symvers in the first pass.

Error log:
    'run.do_shared_workdir.16614' failed with exit code 1:
    DEBUG: cp: cannot stat 'Module.symvers': No such file or directory

This change will check the file Module.symvers existence before copying it.

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.
