I still can't reproduce this on x86_64-pc-linux-gnu.  I notice that you have a
lot of configure flags in your gcc -v output; mine is just

/home/jason/src/trunk/configure -v --with-mpfr=/opt/cfarm/mpfr
--with-gmp=/opt/cfarm/gmp --with-mpc=/opt/cfarm/mpc
--with-libelf=/opt/cfarm/libelf --enable-languages=all,obj-c++
--enable-checking

Can you try rebuilding the compiler with different configure flags and see if
one of them is causing this difference?  I tried building the compiler with all
your configure flags, but it seems to result in a broken stage1 compiler for
me.
