Roland McGrath 03a7582576 * 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.
