exec_startup_get_info RPC from exec_startup.defs in place of old exec_startup from exec.defs. Remove kludge to guess user entry and phdr locations, since the new RPC gives us that info. * sysdeps/generic/_strerror.c: Undo last change.

/* The socket-oriented system calls are handled unusally in Linux.

They are all gated through the single `socketcall' system call number.

which socket function is being called; and the second is a pointer to

the arguments to the specific function.

The .S files for the other calls just #define socket and #include this. */
