Same regression with PowerPC's ppc64e_defconfig, using GCC 8 and GCC 12, as reported with 6.2

Bisection points to "powerpc/boot: Don't always pass -mcpu=powerpc when building 32-bit uImage" (upstream ff7c76f66d8bad4e694c264c789249e1d3a8205d).

Reproducer:
  tuxmake \
    --runtime podman \
    --target-arch powerpc \
    --toolchain gcc-8 \
    --kconfig ppc64e_defconfig \
    config debugkernel dtbs kernel modules xipkernel
