The handling of BR2_LINUX_KERNEL_USE_ARCH_DEFAULT_CONFIG is currently
not doing a proper job: it is selecting ppc64le_defconfig if
BR2_powerpc64le, and using the default of "defconfig" for everything
else.
However:
- Since upstream commit 22f17b02f88b48c01d3ac38d40d2b0b695ab2d10,
which landed in Linux 6.8, the default defconfig is
ppc64le_defconfig and no longer ppc64_defconfig. This means that
despite the condition in linux.mk, we are in fact now always
building ppc64le_defconfig.
- It doesn't handle the 32-bit case, as a 64-bit defconfig gets used
by default. This causes build failures in the autobuilders.
To fix this we explicitly handle BR2_powerpc64le, BR2_powerpc64 and
BR2_powerpc, and use appropriate defconfigs for each case.
