Yes.  This is how I do it.  Place all the generated .so files into the 
library path of the target (i.e. in /lib or /usr/lib).  Then configure 
the target so that you can rsh/rlogin/rcp with no need to supply a 
password (properly configure your .rhosts file).

Then in your home directory of the build machine you need your site.exe 
to be something like:

site.exp
-------------------------
lappend boards_dir "/home/daney/boards"

#
# Determine target machines for all known targets
#

#
# If we're testing GCC, G++ or GDB, then we want to run on all the
# available targets. Otherwise, just test the first one.
#
# set verbose 9
verbose "Global Config File: target_triplet is $target_triplet" 2
global target_list

set target_list { "proton-dave" }
-------------------------

You also need a boards directory that contains something like:

boards/proton-dave.exp
-------------------------------------------
load_base_board_description "unix";

# The generic type of board.
set board_info($board,generic_name) "unix"

# The name used to connect to this machine.
set board_info($board,hostname) "proton-dave"
set board_info($board,rsh_prog) /usr/bin/rsh
set board_info($board,rcp_prog) /usr/bin/rcp

set prefix_dir "/tmp"
-------------------------------------------

Then:
export DEJAGNU=proton-dave
make -k check
