Note this one is not 100% equivalent, because this was using gdb_file_cmd instead of gdb_load for
a reason --  I think because afterwards we're explicitly connecting to a target, while gdb_load may connect
to the target.  I recall patches from Daniel switching from gdb_load to gdb_file_cmd in tests that
don't really need execution for that reason years ago.  ISTR a number of them, but I'm not finding all
that much.  I did find this one, though:

  https://sourceware.org/pipermail/gdb-patches/2010-March/072735.html

So IIRC, what Daniel described back then is I think the reason several tests in
for example gdb.base/ use gdb_file_cmd.

So I grepped for gdb_file_cmd in gdb.base/ and randomly picked gdb.base/list.exp, used
git blame and that led me to this patch:

  https://sourceware.org/pipermail/gdb-patches/2012-June/093697.html

which again is exactly about avoiding gdb_load.

So maybe for the cases we are using gdb_file_cmd today, we should use:

	    clean_restart
	    gdb_file_cmd $binfile

instead of:

	    clean_restart $binfile

?
