After changing --with-host-libstdcxx back to

--with-host-libstdcxx='-static-libgcc -Wl,-Bstatic,-lstdc++,-Bdynamic -lm'

the build succeeds for Linux i386.  I am sure LINKER was set to gcc in this
case.

I am rebuilding without --with-host-libstdcxx to verify that the cross compiler
can be built when LINKER is set to g++ for Linux i386.

After that, I'll try to use a newer GCC on CentoS Linux i386 and try again with
--with-host-libstdcxx='-static-libgcc -static-libstdc++ -lm'.  This seems to be
the more modern equivalent on more recent gcc/g++ compilers.  I found 4.6 and
4.7 compilers include both -static-libgcc and -static-libstdc++ (strings
host-gcc/g++-compiler | grep [-]static[-]).

You can probably reclassify this case from a bug to a feature request.
