Subject: selftests: x86: sysret_ss_attrs doesn't build on a PIE build
From: Shuah Khan <[email protected]>
commit 3346a6a4e5ba8c040360f753b26938cec31a4bdc upstream.
sysret_ss_attrs fails to compile leading x86 test run to fail on systems configured to build using PIE by default. Add -no-pie fix it.
Relocation might still fail if relocated above 4G. For now this change fixes the build and runs x86 tests.
