[PATCH RESEND] riscv : select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY
From: Song Shuai
Date: Fri Sep 23 2022 - 06:03:52 EST
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.
