[xenomai-images 0/7] control applying of no-debug config

[Hongzhan Chen]

1. enable IPIPE_DEBUG uniformly for all arch by default in order to use
uniform method to control it via applying config fragment or not.
2. create config fragment for earch arch to switch debug off.
3. add control to apply config fragment or not.
4. add kas option to control applying config fragment.

[Hongzhan Chen]

Enable IPIPE_DEBUG for arm64 by default. We enable IPIPE_DEBUG for
all arch types uniformly by default in order to controll enabling
and disabling them via same method.

Why is there a *_nodbg,cfg for each Arch? The content for all is the 
same, so IHMO one file should be enough.

Current content is same because we just try to switch off IPIPE_DEBUG for all arches.
But its final purposes is to improve performance for target image to differentiate it from 
debug image, which may include other linux options or arch related options. That is why 
I create *_nodgb.cfg for each arch.

Duplicating is never a good things. So let's keep the common switches in
a common_nodbg.cfg and add the <arch>_nodbg.cfg files once they are needed.
