My build of american-fuzzy-lop fails because clang doesn't
understand the ‘-mcet -fcf-protection’ flags which seem to be
added by RPM.

  clang -O2 -g -pipe -Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 
-Wp,-D_GLIBCXX_ASSERTIONS -fexceptions -fstack-protector-strong 
-grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 
-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -m64 -mtune=generic 
-fasynchronous-unwind-tables -fstack-clash-protection -mcet -fcf-protection 
-Wall -D_FORTIFY_SOURCE=2 -g -Wno-pointer-sign -DAFL_PATH=\"/usr/lib64/afl\" 
-DBIN_PATH=\"/usr/bin\" -DVERSION=\"2.52b\"  afl-clang-fast.c -o 
  clang-6.0: error: unknown argument: '-mcet'
  clang-6.0: error: unknown argument: '-fcf-protection'


This suggests a bug in our RPM configuration.
