This was just a problem with my .ld file.  It is fixed by now.  I do now 
include crt0.o (the one from newlib without modifications) along with my 
own system functions.

However, the main question is still there!  The functions from libc.a 
aren't referenced, but -mads and -myellowknife use the same libc.a. 
This is kind of weird.
