Kristina Martsenko f68022ae0a lkdtm: cfi: Make PAC test work with GCC 7 and 8 ... The CFI test uses the branch-protection=none compiler attribute to disable PAC return address protection on a function. While newer GCC versions support this attribute, older versions (GCC 7 and 8) instead supported the sign-return-address=none attribute, leading to a build failure when the test is built with older compilers. Fix it by checking which attribute is supported and using the correct one.
