+Subject: [PATCH] CMakeLists.txt: Improve checking for CFLAGS
+
+The previous log wasn't clear:
+-- Performing Test found
+-- Performing Test found - Success
+-- Performing Test found
+-- Performing Test found - Success
+-- Performing Test found
+-- Performing Test found - Failed
+
+Use a new var compiler-supports${flag} will make it more clear:
+-- Performing Test compiler-supports-fno-strict-overflow
+-- Performing Test compiler-supports-fno-strict-overflow - Success
+-- Performing Test compiler-supports-fno-delete-null-pointer-checks
+-- Performing Test compiler-supports-fno-delete-null-pointer-checks - Success
+-- Performing Test compiler-supports-fhardened
+-- Performing Test compiler-supports-fhardened - Failed
+
+Upstream-Status: Backport [https://github.com/rpm-software-management/rpm/commit/e14502834fe6a9c6c9a439401ac3d2c8fd979267]
