If you had an extremely old version of setup, it might not automatically
choose binutils as a dependency for gcc.
Additional packages are required to build gcc, such as diffutils, make,
automake, texinfo, gmp, mpfr (development versions).  This is not implied
by "make gcc work correctly."
After installing automake, it is necessary to over-write autoconf with
autoconf 2.59 which is easily built from source, as gcc build requires
that specific version.
I'd be surprised if debian had a specific automatic dependency setup for
gcc build, although more of the tools would be included in the base
package selection, or come in automatically when installing gcc.
