I applied the patch at http://gcc.gnu.org/ml/gcc-patches/2011-10/msg02441.html
(no difference to the problem at hand).
The only definite thing I've spotted so far is in the args file:
-B\ /Volumes/ScratchCS/gcc-4-7-trunk-build/gcc/
if I try to do
./gcc/xgcc @<path/to/args/file
with this in it; xgcc doesn't find lto1.
If I replace the escaped space with either a space or a new line it works.
