Where you found that the gcc-4.7.2 and binutils-2.23.1 sources are in 
sync so
that they can be combined and be built together?

A quick googling with this subject told in :

http://stackoverflow.com/questions/1726042/recipe-for-compiling-binutils-gcc-together

the following :

"Doing this with gcc 4.7.2, with binutils-2.22 and 
contrib/download_prerequisites for gmp,
mpc,mpfr; recipe works, but gcc fails to build with -flto, resulting in: 
collect2: fatal error:
cannot find 'ld'. To rectify that, make a symbolic link ld -> ld-new in 
your ...prefix/bin directory."

I don't know what the "contrib/download_prerequisites" says about the 
binutils version
for gcc-4.7.2 if even anything but a simple sanity check with the 
release dates of the 1st src
releases :

gcc-4.7.0 - 22.3.2012
binutils-2.23 - 22.10.2012

tells that the latter wasn't available when the former was released!
