我一直在尝试在新的Ubuntu 20.04计算机上构建特定版本的GCC（8.3.0）。但是，当我按照以下链接的步骤操作时：https://gcc.gnu.org/wiki/InstallingGCC，我遇到了Makefile错误。
步骤：
wget https://ftp.gnu.org/gnu/gcc/gcc-8.3.0/gcc-8.3.0.tar.xz
tar xf gcc-8.3.0.tar.xz
cd gcc-8.3.0
./contrib/download_prerequisites
cd .. ; mkdir build ; cd build
../gcc-8.3.0/configure --prefix=/opt/gcc-8.3 --enable-languages=c,c++,fortran --disable-multilib

然后最后，使用make -j 8，并筛选出巨大的输出，我得到以下错误：
make -j8

有什么想法吗？我还尝试使用CC = gcc-7和CXX = g ++-7环境变量进行配置，并收到相同的结果（它仍使用xgcc）。交叉编译器xgcc似乎是错误的。
