Linux kernel 5.10 requires a gcc version beyond 4.9 in order to build
it. So to build it we use a third party toolchain called devtoolset-8
which contains gcc version 8.3. We only use this toolchain for the
kernel and kernel modules, leaving the original gcc 4.8.5 in place for
everything else.
scl-utils-build is required by devtoolset-8.
