Patches to fix linux-x-i960-vxworks5.0 build failure.

	* remote-vx.c (net_read_registers, net_write_registers, vx_xver_memory,
	vx_resume, vx_attach, vx_detach, vx_kill): Change errno to errno_num.
	* vx-share/xdr_ptrace.c (xdr_ptrace_return): Likewise.
	* vx-share/xdr_ptrace.h (struct ptrace_return): Likewise.
