I guess it would be a lot easier to create a combined source tree with 
gcc, binutils and newlib and to everything only once.

Download and unpack binutils,gcc,gmp,mpfr,mpc,isl(optional) and newlib.

$ cd gcc-*
$ ln -s ../gmp-* gmp
$ ln -s ../mpfr-* mpfr
$ ln -s ../mpc-* mpc
$ ln -s ../isl-* isl

$ for i in bfd binutils gas ld opcodes; do ln -s ../binutils-*/$i; done

for newlib
$ ln -s ../newlib-*/newlib
$ ln -s ../newlib-*/libgloss


$ mkdir ${HOME}/obj; cd ${HOME}/obj
$ (TARGET=m68k-elf && ${HOME}/src/gcc-*/configure --prefix=/${TARGET} 
--libexecdir=/${TARGET}/lib --target=${TARGET} --enable-languages=c,c++ 
--disable-libstdcxx-pch --with-newlib)

(optional: fix compiler flags)
sed -i 's/\-g /-pipe /' Makefile
sed -i '/^CFLAGS / s/$/ -march=native/' Makefile
sed -i '/^CXXFLAGS / s/$/ -march=native/' Makefile
sed -i '/^CFLAGS_FOR_BUILD/ s/$/ -march=native/' Makefile
sed -i '/^CXXFLAGS_FOR_BUILD/ s/$/ -march=native/' Makefile

Compile and install into staging area
$ make -j$(nproc)
$ make -j2 install-strip DESTDIR=$(pwd)/dest

(install-strip might fail for libgloss, so the workaround I've used is 
to do a "make install -j2" first, and a "make -j2 install-strip -k" 
aferwords)
