I'm not building linux directly, but BPF programs that indirectly uses
clang with bcc

On fedora you can install bcc-tools and run
e.g. /usr/share/bcc/tools/execsnoop that will compile something at
runtime.
If the package isn't available for your distro you can just install bcc
and run the script from their repo[1]
