I couldn't find that, either. It appears that they don't even try to
support downlevel binutils. Our gcc packages use any old linker at
their own peril.

They provide a facility to build the linker and compiler together,
it's just that the binutils and gcc are maintained and distributed by
different teams, so you have to merge the distributions by hand to do
that (or use CVS). "gcc" will also pick up and hard code the path to
installed "as" and "ld" at configure-time if they are obviously
family, that is, if they are found in "${prefix}${target}/bin".

There's a similar problem with the gcc-2.95.3 package. (See the
neighboring thread on that, which includes a couple of alternative
solutions for pkgsrc).
