[PATCH 2/3] Enable ptrace events on new child processes.

[John Baldwin <jhb@FreeBSD.org>]

New child processes on FreeBSD do not inherit optional ptrace events
such as fork and LWP events from the parent process.  Instead,
explicitly enable events on new children when reporting a fork
event.

gdb/ChangeLog:

	* fbsd-nat.c (fbsd_wait): Use "fbsd_enable_proc_events" on
	new child processes.
