[PATCH v3 2/2] selftests/bpf: Enable private stack tests for powerpc64

[adubey at linux.ibm.com]

From: Abhishek Dubey <adubey at linux.ibm.com>

With support of private stack, relevant tests must pass
on powerpc64.

#./test_progs -t struct_ops_private_stack
#434/1   struct_ops_private_stack/private_stack:OK
#434/2   struct_ops_private_stack/private_stack_fail:OK
#434/3   struct_ops_private_stack/private_stack_recur:OK
#434     struct_ops_private_stack:OK
Summary: 1/3 PASSED, 0 SKIPPED, 0 FAILED

v2->v3:
  Enable testcase using __powerpc64__ instead of __TARGET_ARCH_powerpc,
  to prevent it getting invoked on powerpc32

[v2]: https://lore.kernel.org/bpf/20260225153950.15331-1-adubey@linux.ibm.com
