some (many?) targets require some C library headers before they can build for 
the target at all.  we used to do cross-compiling where we'd skip the C library 
headers, but the amount of patching/hacks we had to add to GCC got 
unmaintainable, and the code base got more and more hostile to the concept 
(just search for inhibit_libc).  how exactly are you building the first GCC 
w/out any C library headers ?
