hurd: Avoid more libc.so local PLTs

	* hurd/catch-signal.c (__hurd_catch_signal): Call __libc_siglongjmp
	instead if siglongjmp.
	(hurd_safe_memmove): Call __libc_longjmp instead of longjmp.
	* hurd/hurdfault.c (faulted): Call __libc_longjmp instead of longjmp.
	* include/setjmp.h (__libc_siglongjmp, __libc_longjmp): New hidden
	prototypes.
	* libio/iolibio.h (_IO_puts): New hidden prototype.
	* libio/ioputs.c (_IO_puts): New hidden def.
	* setjmp/longjmp.c (__libc_longjmp, __libc_siglongjmp): New hidden
	defs.
	* sysdeps/mach/hurd/sigwait.c (__sigwait): Call __libc_longjmp instead
	of longjmp.
