[PATCH v2 1/8] tools build: Align warning options with perf

Leo Yan
2025-09-30T16:55:17Z

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.
