Great, thanks. Here's how I installed GCC 8.1 from crosstool:
listings: https://www.kernel.org/pub/tools/crosstool/
wget https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz
pushd /opt/cross/
tar -xf ~/tmp/crosstool/x86_64-gcc-8.1.0-nolibc-x86_64-linux.tar.xz
In top level create GNUMakefile:
CROSS_COMPILE=/opt/cross/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-
include Makefile
