[Naresh Kamboju]

On stable rc 5.10 the ppc defconfig build failed due to below errors/warnings.

make --silent --keep-going --jobs=8

CROSS_COMPILE=powerpc64le-linux-gnu- 'CC=sccache
powerpc64le-linux-gnu-gcc' 'HOSTCC=sccache gcc'
arch/powerpc/lib/sstep.c: In function 'analyse_instr':
arch/powerpc/lib/sstep.c:1415:3: error: label 'unknown_opcode' used
but not defined
   goto unknown_opcode;

Steps to reproduce:
---------------------
# TuxMake is a command line tool and Python library that provides
# portable and repeatable Linux kernel builds across a variety of
# architectures, toolchains, kernel configurations, and make targets.
#
# TuxMake supports the concept of runtimes.
# See https://docs.tuxmake.org/runtimes/, for that to work it requires
# that you install podman or docker on your system.
#
# To install tuxmake on your system globally:
# sudo pip3 install -U tuxmake
#
# See https://docs.tuxmake.org/ for complete documentation.

tuxmake --runtime podman --target-arch powerpc --toolchain gcc-9
--kconfig defconfig
