riscv now uses -fpatchable-function-entry with dynamic ftrace after the `afc76b8b8` commit, which means recordmcount shouldn't be called to create the __mcount_loc section before the vmlinux linking.
We should select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY to tell Makefile not to run recordmcount.
