I've been trying to build a specific version of GCC (8.3.0) on a new Ubuntu 20.04 machine. However, when I follow the steps at the following link: https://gcc.gnu.org/wiki/InstallingGCC I run into a Makefile error.
Steps:
wget https://ftp.gnu.org/gnu/gcc/gcc-8.3.0/gcc-8.3.0.tar.xztar xf gcc-8.3.0.tar.xzcd gcc-8.3.0./contrib/download_prerequisitescd .. ; mkdir build ; cd build../gcc-8.3.0/configure --prefix=/opt/gcc-8.3 --enable-languages=c,c++,fortran --disable-multilibConfig output:

I've also tried configuring with CC=gcc-7 and CXX=g++-7 enviro variables and received the same result (it still uses xgcc). This seems to be an error with the cross compiler xgcc.
