I initially had the same question. Then, I assumed this new runtime test
has been simply copied from the existing test_bcc:
https://gitlab.com/buildroot.org/buildroot/-/blob/master/support/testing/tests/package/test_bcc.py
which was written with kernel 6.6.32, which was the latest LTS at that 
time.

Once the next 2026.08 release will be complete, I think we will do a 
cleanup
in runtime tests, to add a Aarch64 builtin kernel at the latest LTS. So 
all
those runtime tests will be updated.
