[PATCH] perf build: Report failure for testing feature libopencsd

From: Leo Yan
Date: Thu Sep 02 2021 - 03:44:21 EST


When build perf tool with passing option 'CORESIGHT=1' explicitly, if
the feature test fails for library libopencsd, the build doesn't
complain the feature failure and continue to build the tool with
disabling the CoreSight feature insteadly.

This patch changes the building behaviour, when build perf tool with the
option 'CORESIGHT=1' and detect the failure for testing feature
libopencsd, the build process will be aborted and it shows the complaint
info.
