[rfa/remote] Reread symbols on 'target remote'

[Daniel Jacobowitz <drow@false.org>]

Right now chng-syms.exp fails for remote targets, because "run" causes the
executable to be reread but "target remote" doesn't.  I thought I'd already
submitted a patch for this, a year or two ago, but I can't find it in my
archives anywhere.  This patch just adds a matching check to remote_open_1.

This patch, and another I'm about to send separately, fix chng-syms.exp for
gdbserver targets.

OK?

	* remote.c (remote_open_1): Reopen the exec file and reread symbols
	if necessary.
