spelling out "who am i" is more portable

Sorry, but I have no answer for this - csh's on older sysV's can be flaky.
There are lots of quotes here - maybe check that.

But some changes in logic would be a quick fix to do the same thing:

<setting stuff>
if ($user2 == 'root') then
     set prompt = $host':'$user1' (root) # '
else
     set prompt = $host':'$user1'% '
endif

It's as portable and (slightly) more efficient.

If you set your SHELL variable to /bin/sh (and have no prompt setting stuff in
your .profile) before running make you won't have this problem - or you can
take the prompt stuff and put it in your .login, but obviously you won't be able
to do the type of prompt stuff you describe above. 

If you do use the SHELL trick, remember to set your SHELL variable back after
running make - otherwise your su's will run the Bourne shell.
