[commit/testsuite] Improve printcmds.exp with remote targets

[Daniel Jacobowitz]

With some board files, like native, gdb_load just loads the file.
With others, like a typical remote target that uses "load" but not
"run", it connects to the target and sends "load".  I once
changed gdbserver to avoid this, because of so many assumptions that
the target was not running after gdb_load, but we still have a bunch
of embedded board files that work this way.

The trick for tests that rely on the target not running is to use
gdb_file_cmd instead of gdb_load, so that's how I fixed printcmds.exp.

Tested on arm-none-eabi, committed on trunk.

	* gdb.base/printcmds.exp: Use gdb_file_cmd instead of gdb_load.
	Use gdb_load later.
