Interesting.  I found this script in LEDE:

  https://git.lede-project.org/?p=source.git;a=blob;f=scripts/strip-kmod.sh;hb=HEAD

But it's indeed possible that it's not run for kernel modules that are
built outside of the core system.  I will take a closer look.

Can you check that, for instance, the kmod-udptunnel modules are properly
stripped?
