Indeed ... having followed your instructions (on 64-bit Ubuntu 12.10) I found 
myself first faced with the "cannot find crti.o" I'd encountered before.

I "fixed" that by Alex Petersen's suggestion of symlinking 
/usr/lib/x86_64-linux-gnu/crt*.o to /usr/lib/crt*.o (which hopefully won't break 
anything) and the build proceeded on that basis, but finally fell over with 
another error, I think while trying to build gcov-dump (it's a bit hard to tell 
with such verbose compilation statements as GCC has):
