I think doing combined tree builds (with binutils and GCC in the same
source tree) is only guaranteed to work with the top-of-tree versions
of each, otherwise various configury files don't match.

The simplest way I know to achieve what you seem to want is to install
binutils first, separately, to $PREFIX, then configure and install GCC
to the same $PREFIX. During its configuration GCC will notice that
binutils is installed in its final destination and will be configured
to automatically use $PREFIX/bin/as and $PREFIX/bin/ld rather than the
usual versions in your $PATH.
