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]
