It looks like you don't have gcc installed.
In case you specifically need gcc-7, you can install it with
sudo apt install gcc-7 Otherwise you can install the package gcc or build-essential(which would provide a later version of gcc).
In case this program bootstrap wants to have gcc-7 at the specific location /usr/local/bin/ and that cannot be changed, you can symlink it.
sudo ln -s /usr/bin/gcc-7 /usr/local/bin/gcc-7 By default, new installation of Ubuntu does not have C compiler installed (nor any other tools needed for compiling programs). To install it, you need to install build-essential package:
sudo apt-get install build-essential
