Yeah, I got that bug too, but on a different file.  I've pulled up 
http://www.gnu.org/software/make/manual/html_mono/make.html and am slowly 
reading through it because the new changes to the makefile infrastructure 
seem to be kind of brittle...

Why on earth are you trying to make an assembly file?  We don't do that 
anywhere in the tree, to we?  It's not portable...

Why would we want to do this?

Ordinarily I don't care much about our makefile infrastructure getting bigger 
our our build taking up more space and more memory, because what we're trying 
to optimize is the generated binary.  But I also _hate_ complexity, and the 
build infrastructure has been growing huge quantities of it recently, for 
reasons I don't properly understand.  I don't appear to have the luxury of 
ignorance here anymore...
