[PATCH 6.6 039/201] tools build: Align warning options with perf

[Greg Kroah-Hartman]

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

------------------

From: Leo Yan <leo.yan at arm.com>

[ 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.
