Even target_ops hook `can_use_agent' and `use_agent' are implemented in
inf-child.c by patch

  [PATCH 8/9] impl of use_agent and can_use_agent in linux-nat
  http://sourceware.org/ml/gdb-patches/2012-02/msg00553.html

I am still inclined to implement static_tracepoint_markers_by_strid in
linux-nat, because there is no agent at all for non-linux system.
Although agent itself is quite generic to all unix system, it still
needs de-couple from tracepoint.  On the other hand, UST is
Linux-specific, so it is better to keep
static_tracepoint_markers_by_strid implemented in linux-nat.
