+Subject: [PATCH] cmake: correct PIE support detection, add error output for
+ debugging `check_pie_supported` only uses the `OUTPUT_VARIABLE` to to signify
+ errors if PIE is actually supported is signaled by
+ `CMAKE_<lang>_LINK_PIE_SUPPORTED`.
+
+Checking if `OUTPUT_VARIABLE` is empty is not enough either since the check
+is bypassed if its results are cached but the output variable is not cached.
