Error compiling GCC for i686-elf on Windows(MinGW)

Question

I am trying to compile binutils and GCC (for windows) as per this tutorial. The binutils compilation has finished without errors , however GCC has failed

Steps I've taken
Installed MinGW with the dependencies specified in the tutorial. Installed the GCC and binutils source code and unpacked them in $HOME/src folder
And in the MinGW shell:

export PREFIX="$HOME/opt/cross"
export TARGET=i686-elf
export PATH="$PREFIX/bin:$PATH"

cd $HOME/src
 
mkdir build-binutils
cd build-binutils
../binutils-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror
make
make install

so far everything went without any errors

cd $HOME/src
 
# The $PREFIX/bin dir _must_ be in the PATH. We did that above.
which -- $TARGET-as || echo $TARGET-as is not in the PATH
 
mkdir build-gcc
cd build-gcc
../gcc-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++ --without-headers
make all-gcc
make all-target-libgcc
make install-gcc
make install-target-libgcc

Firstly, the which command failed giving unrecognized command -- . I ensured that path_to_sysm_user/opt/cross/bin was added to PATH and moved on Then in make all-gcc warnings and errors popped up:
