Yes, for a hand-built kernel/modules, you need:
CONFIG_DEBUG_INFO=y
CONFIG_KPROBES=y

And the resulting "vmlinux" file must be copied into one of the places
elfutils searches for it:
"""
- systemtap looks for the debug info in these locations:
  /boot/vmlinux-`uname -r`
  /usr/lib/debug/lib/modules/`uname -r`/vmlinux
  /lib/modules/`uname -r`/vmlinux
