Do you have an access to such "arch" machine?
The running itself should be done on the target ("arch") machine.

AFAIK, if you don't have such machine, you won't be able to run all the
"need-to-be-executed" tests.
Only the tests that not suppose to run will be tested (like
compilation-only tests).

If you do have such machine, you need to compile on the host (current)
machine and run the binaries remotely.
That can be done by:
1. Write in your .shrc/.bashrc/...: setenv/export DEJAGNU
/home/<$USER>/etc/site.exp
2. Write in /home/<$USER>/etc/site.exp:
append boards_dir "/home/<$USER>/etc/boards"
case "$target_triplet" in {
      { "arch*-*-*" } { set target_list { <name of the machine> } }
}
3. Create a file /home/<$USER>/etc/boards/<name of the machine> and write
in it:
load_generic_config "unix"  (or anything else...)
set_board_info hostname "<name of the machine>"
set_board_info username <user>
set_board_info rsh_prog /usr/bin/ssh  (or anything else...)
set_board_info rcp_prog /usr/bin/scp  (or anything else...)
<Here can come other needed settings...>

Now, actually, you can run the testsuite (as usual, with "make -k check",
or similar command).
In case you have a promt for a passphrase every time you logon to the
target machine, you'll need to type the password for each test.
That is very annoying.
In order to solve that you can use ssa-agent:
1. Type: ssh-keygen -t rsa
2. Type:eval `/usr/bin/ssh-agent  -s`
3. Type: /usr/bin/ssh-add < /dev/null
4. copy your ~/.ssh/id_rsa.pub file (generated in the above process) to the
file ~/.ssh/authorized_keys on the machine(s) you wish to be able to access
without a password.

Now you can run "make check" "as usual".

HTH. Good luck,
Tehila.
