'-mabi=elfv2' is not added to clang's invocations when
CONFIG_PPC64_ELF_ABI_V2 is enabled, resulting in the generation of elfv1
code, as evidenced by the orphan section warnings/errors:
ld.lld: error: vmlinux.a(arch/powerpc/kernel/prom_init.o):(.opd) is being
placed in '.opd'
ld.lld: error:
Commit 5017b4594672 ("powerpc/64: Option to build big-endian with ELFv2
ABI") restricted the ELFv2 ABI configuration such that it can only be
selected when linking with ld.bfd, due to lack of testing with LLVM.
ld.lld can link ELFv2 kernels without any issues; in fact, it is the
only ABI that
it but clang
errors out. Only provide '-mabi=elfv2' when CONFIG_PPC64_BOOT_WRAPPER is
enabled, which is the only way '-mabi=elfv2' will be useful.

To eliminate the warning, remove -fno-stack-clash-protection from

flags previously.
