	* sysdeps/unix/sysv/linux/fork-gen.c: Renamed to...
	* sysdeps/unix/sysv/linux/libc_pthread_init.c: ...this.
	Initialize __libc_locking_needed.
	* init.c (__pthread_initialize_minimal): Call __libc_pthread_init
	instead of __register_pthread_fork_handler.
	* sysdeps/pthread/bits/libc-lock.h: Declare __libc_locking_needed.
	* sysdeps/unix/sysv/linux/Makefile (sysdep_routimes): Replace
	fork-gen with libc_pthread_init.
	* sysdeps/unix/sysv/linux/Versions: Use __libc_pthread_init instead
	of __register_pthread_fork_handler.
	* sysdeps/unix/sysv/linux/fork.h: Declare __libc_pthread_init instead
	of __register_pthread_fork_handler.
	* sysdeps/unix/sysv/linux/i386/lowlevellock.h: Use
	__libc_locking_needed to determine whether lock prefix can be avoided.
	* sysdeps/unix/sysv/linux/i386/i486/libc-lowlevellock.S: Likewise.
