powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2
commit
482b718a84f08b6fc84879c3e90cc57dba11c115 upstream.
Commit
8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian
builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way
that is incompatible with the current code for the PS3's LV1 hypervisor
calls.
This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.
Fixes run time errors like these:
