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.
