#     selftests/sigaltstack: Fix ppc64 GCC build
#     
#     Building the sigaltstack test with GCC on 64-bit powerpc errors with:
#     
#       gcc -Wall     sas.c  -o /home/michael/linux/.build/kselftest/sigaltstack/sas
#       In file included from sas.c:23:
#       current_stack_pointer.h:22:2: error: #error "implement current_stack_pointer equivalent"
#          22 | #error "implement current_stack_pointer equivalent"
#             |  ^~~~~
#       sas.c: In function ‘my_usr1’:
#       sas.c:50:13: error: ‘sp’ undeclared (first use in this function); did you mean ‘p’?
#          50 |         if (sp < (unsigned long)sstack ||
#             |             ^~
#     
#     This happens because GCC doesn't define __ppc__ for 64-bit builds, only
#     32-bit builds. Instead use __powerpc__ to detect powerpc builds, which
#     is defined by clang and GCC for 64-bit and 32-bit builds.
