* sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER):
New macro. (PSEUDO): Use it instead of SYSCALL_PIC_SETUP and jmp syscall_error. * sysdeps/unix/sysv/linux/i386/sysdep.S (__syscall_error): Define only #ifndef PIC. * Makeconfig (built-program-cmd): New variable. * sunrpc/Makefile (rpcgen-cmd): Use $(built-program-cmd). * time/Makefile (zic-cmd): Likewise. * hurd/Makefile (user-interfaces): Add hurd/exec_startup.
