x86/cet: Add -fcf-protection=none before -fcf-protection=branch
When shadow stack is enabled, some CET tests failed when compiled with GCC 14: FAIL: elf/tst-cet-legacy-4 FAIL: elf/tst-cet-legacy-5a FAIL: elf/tst-cet-legacy-6a which are caused by https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113039 These tests use -fcf-protection -fcf-protection=branch and assume that -fcf-protection=branch will override -fcf-protection. But this GCC 14 commit: https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=1c6231c05bdcca changed the -fcf-protection behavior such that -fcf-protection -fcf-protection=branch is treated the same as -fcf-protection Use -fcf-protection -fcf-protection=none -fcf-protection=branch as the workaround. This fixes BZ #31187. Tested with GCC 13 and GCC 14 on Intel Tiger Lake. Reviewed-by: Noah Goldstein <goldstein.w.n@gmail.com>
