I think you need newlib (or a symlink to it) under your gcc-2.95.2
directory.  You'll need --with-newlib.  If I remember correctly, LANGUAGES
may be obsoleted and replaced by --enable languages.

Below is what I usually do for h8300-hms.  I just changed it to m68k-coff.

tar xfz gcc-2.95.3.tar.gz
tar xfz newlib-1.9.0.tar.gz
cd gcc-2.95.3
ln -s ../newlib-1.9.0/newlib .
mkdir objdir
cd objdir
../configure \
        --prefix=/usr/local --target=m68k-coff \
        --enable-languages="c,c++" --with-newlib
gmake CFLAGS="-O2 -fno-strength-reduce -fomit-frame-pointer" all
gmake install #this has to be done by root
