While you can bootstrap from SML/NJ, you would be much better off 
starting from a MLton binary.  But, we don't seem to have a Linux/PowerPC 
binary availabe.  If you are using Debian, there are binary packages of 
the latest MLton release in testing and unstable for PowerPC.

My guess is that the SML/NJ compile failed.  It seems that when SML/NJ 
exits, it always returns 'success', even if the last invoked command 
failed, so make will assume that the SML/NJ compile succeeded.  You should 
scan back through the output of 'make nj-mlton' and verify that the SML/NJ 
compile succeeded.
