You can test a cross compiler if you have some way of copying a test 
executable to the i370 system, running it and getting its output and exit 
status back (actually you don't need to be able to get the exit status 
since DejaGnu has wrappers to include it in the output if needed).  There 
is no need for the target to be able to run shell scripts or makes.  You 
would need to write your own DejaGnu board file that deals with copying 
to/from the i370 system and running programs there.  The testsuite 
routinely runs for much more limited embedded systems (using appropriate 
board files).
