	* infrun.c (handle_inferior_event): When handling a
	TARGET_WAITKIND_FORKED, detach breakpoints from the fork child
	immediatelly.
	* linux-nat.c (linux_child_follow_fork): Only detach breakpoint
	from the child if vforking.
	* inf-ptrace.c (inf_ptrace_follow_fork): No need to detach
	breakpoints from the child here.

	* gdb.base/foll-fork.c: Include stdlib.h.  Add markers for
	`gdb_get_line_number'.  Call `callee' in both parent and child.
	* gdb.base/foll-fork.exp (catch_fork_child_follow): Use
	`gdb_get_line_number' instead of hardcoding line numbers.
	(catch_fork_unpatch_child): New procedure to test detaching
	breakpoints from child fork.
	(tcatch_fork_parent_follow): Use `gdb_get_line_number' instead of
	hardcoding line numbers.
	(do_fork_tests): Run `catch_fork_unpatch_child'.
