MTU-tests: Loading via tc seems not to support global vars
...
This code only works because LLVM optimize it as a constant.
As soon at I try to use it as variable it breaks.

MTU-tests: iproute2 'tc' tool doesn't understand BTF debug info
...
It still works when loading, but results in a huge warning
which is really annoying.
Add a Makefile hack to strip the object file.

lsm-nobpf: Check for presence of BPF LSM before loading
...
If the BPF LSM is compiled-in but not enabled, the loading of the BPF
program will succeed, but it won't actually do anything. Detect this
and abort rather than silently not working.
