selftests/sigaltstack: Fix ppc64 GCC build
commit 17c743b9da9e0d073ff19fd5313f521744514939 upstream.
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.
