Given that subtle gcc changes sometimes interact unfortunately with
kernel compilation, I *would not* do kernel compilation from CentOS 8
Stream based systems. Locking down the build environment for kernels
is especially vital because it can be *very* difficult to sort out the
subtleties of the "include" file changes of critical tools like gcc.

Our friends at Red Hat already do something like this for "real-time"
kernels referred to as "kernel-rt", which is where I last encountered
the need for hand-tuning kernels. It's in the "centos/8/rt/" in the
yum merrors.
