Shuah Khan 3346a6a4e5 selftests: x86: sysret_ss_attrs doesn't build on a PIE build
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.
