uhm. where do you expect a target compiled file (ie. one that's run at 
boot time) to use libc?

I'm _not_ talking about the host compiler - here everything works fine, 
after all, there's no linker abuse going on there, just the average 
compile+link process.

Compiling gcc 4.2 (or 4.1.2) with gnu as and gnu ld in the back end 
resulted in compile errors here, when I tried to do a "normal" build.

The grub (0.95 btw!) in the OpenSolaris tree features a parallel 
makefile hierarchy that uses /usr/sfw/bin/gcc (which uses Sun tools in 
the back end) and, it seems, manual invocations of gnu ld.
so here you are - they basically link by hand
