selftests: vDSO: fix vdso_config for powerpc
[ Upstream commit 7d297c419b08eafa69ce27243ee9bbecab4fcaa4 ]
Running vdso_test_correctness on powerpc64 gives the following warning:
~ # ./vdso_test_correctness
Warning: failed to find clock_gettime64 in vDSO
This is because vdso_test_correctness was built with VDSO_32BIT defined.
__powerpc__ macro is defined on both powerpc32 and powerpc64 so
__powerpc64__ needs to be checked first in vdso_config.h
