Failure to compile elf toolchain in Ubuntu Xenial chroot

[ioerror]

I attempted to build the toolchain using an Ubuntu Xenial chroot configured as follows:

sudo apt install -y debootstrap
debootstrap xenial xenial-chroot
sudo chroot xenial-chroot add-apt-repository universe
sudo chroot xenial-chroot apt update
sudo chroot xenial-chroot apt install -y build-essential wget unzip bc git
sudo chroot xenial-chroot apt install -y texinfo bison flex libgmp-dev libmpfr-dev libmpc-dev
sudo chroot xenial-chroot
# Inside Xenial chroot
git clone https://github.com/c-sky/toolchain-build
cd toolchain-build

Fetching the source is sucessful:

./build-csky-gcc.py --tos=elf --init

However as with #2, #3, and #4 - the mklink target isn't valid:

====> toolchain components = ['binutils', 'gcc', 'minilibc', 'gdb', 'mklink']

<-- component 'binutils' source code url ['/root/toolchain-build/source//binutils'] is ok

<-- component 'gcc' source code url ['/root/toolchain-build/source//gcc'] is ok

--> git clone https://github.com/c-sky/toolchain-build.git /root/toolchain-build/source//minilibc  

<-- component 'gdb' source code url ['/root/toolchain-build/source//gdb'] is ok

<-- component 'mklink' source code url ['/root/toolchain-build/source//mklink'] is not valid

Building fails after the gcc.1 component:

./build-csky-gcc.py --tos=elf 

====> components chain = ['binutils', 'gcc.0', 'minilibc', 'gcc', 'gdb', 'mklink']

====> start building component 'binutils' ... ...
<-- current component 'binutils.0' has finished

====> start building component 'gcc.0' ... ...
--> current building platform/os is "linux2"
<-- current component 'gcc.0' has finished

====> start building component 'minilibc' ... ...
<-- current component 'minilibc.0' has finished

====> start building component 'gcc.1' ... ...
