#     selftests/powerpc: Fix wild_bctr test to work on ppc64
#     
#     The selftest I recently added to test branching to an out-of-bounds
#     NIP doesn't work on 64-bit big endian. It does fail but not in the
#     right way. That is it SEGVs trying to load from the opd at BAD_NIP,
#     but it never gets as far as branching to BAD_NIP.
#     
#     To fix it we need to create an opd which is reachable but which holds
#     the bad address.
#     
#     Fixes: b7683fc66eba ("selftests/powerpc: Add a test of wild bctr")
