Hi Vaibhav,

Nice to see some people are still building QEMU at IBM ;-)

Kowshik reported that building qemu with GCC 12.2.1 for 'ppc64-softmmu'
target is failing due to following build warnings:

  ../target/ppc/cpu_init.c:7018:13: error: 'ppc_restore_state_to_opc' defined 
but not used [-Werror=unused-function]
  7018 | static void ppc_restore_state_to_opc(CPUState *cs,

Fix this by wrapping these function definitions in 'ifdef CONFIG_TCG' so that
they are only defined if qemu is compiled with '--enable-tcg'

Interestingly this config isn't covered in .gitlab-ci.d/custom-runners/ubuntu-20.04-s390x.yml.
