#     powerpc/signal: Fix possible build failure with unsafe_copy_fpr_{to/from}_user
#     
#     When neither CONFIG_VSX nor CONFIG_PPC_FPU_REGS are selected,
#     unsafe_copy_fpr_to_user() and unsafe_copy_fpr_from_user() are
#     doing nothing.
#     
#     Then, unless the 'label' operand is used elsewhere, GCC complains
#     about it being defined but not used.
#     
#     To fix that, add an impossible 'goto label'.
