Did you use --disable-target-libitm?

I used

--prefix=/usr/local --enable-clocale=gnu --with-system-zlib --enable-shared
--with-demangler-in-ld --with-fpmath=sse
--enable-languages=c,c++,fortran,java,lto,objc

C++ compiler is disabled for stage 1 and system C++ compiler
is used for stage 2.

Same for my tests on i386-unknown-freebsd10 and x86_64-unknown-freebsd8
and minimal configure options --prefix and --with-gmp only.

The bootstrapping compiler is GCC 4.2.  Is it possible that this, the
bootstrapping compiler being older, makes a difference somehow?  I see
this in the failing invocation which does not use an absolute path name
for g++!
