[PATCH RESEND] riscv : select FTRACE_MCOUNT_USE_PATCHABLE_FUNCTION_ENTRY

[Song Shuai <suagrfillet@gmail.com>]

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.
