5.15-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 53d067feb8c4f16d1f24ce3f4df4450bb18c555f ]
The feature test programs are built without enabling '-Wall -Werror' options. As a result, a feature may appear to be available, but later building in perf can fail with stricter checks.
Make the feature test program use the same warning options as perf.
