What steps will reproduce the problem?
What is the expected output? What do you see instead?

In src/Make.pkg, $(elem) is empty even though $(TARG) is not.

What is your $GOOS?  $GOARCH?

linux_386

Which revision are you sync'ed to?  (hg log -l 1)

Please provide any additional information below.

GNU Make 3.8.0's lastword function appears to be broken. I've replaced it 
with the alternative suggested in Make's manual and that worked (even 
though the manual states the two are identical). Patch attached.

Sorry, this should read GNU Make 3.80, not 3.8.0

I think we can safely say that we need make 3.81.
I've suggested http://golang.org/cl/154062, but it might be too much bother. 
On the other hand, it might save some people the debugging time in future.
Thanks!
