[avr-gcc-list] Trunk broken for AVR Target?

I am trying to build recent snapshot gcc-4.7-20110604 without any patches. 
Build fails for libgcc2.c. Unless I am doing something wrong, I think the trunk 
is broken. Can someone confirm this?

checking for suffix of object files... configure: error: in 
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.
make[1]: *** [configure-target-libgcc] Error 1


Further probing shows that dwarf-2 information generation is affected.

configure:3056: /home/anitha/gcc-4.7-20110604/objdir/./gcc/xgcc 
-B/home/anitha/gcc-4.7-20110604/objdir/./gcc/ -B/usr/local/avr/bin/ 
-B/usr/local/avr/lib/ -isystem /usr/local/avr/include -isystem 
/usr/local/avr/sys-include    -o conftest -g -O2   conftest.c  >&5
conftest.c: In function 'main':
conftest.c:16:1: internal compiler error: in 
compute_frame_pointer_to_fb_displacement, at dwarf2out.c:18342


I have done some more analysis on the origin of this error, but before that I 
think it is a good idea if someone can confirm that the build is broken.
