scripts/gdb: multi arch lx_current

[Thiébaud Weksteen]

Hi Jan,

I've been working on lx_current and cpus.py to support other architectures 
than just x86. From my understanding, current/get_current are not available 
with the default debug option (-g). We could either modify that level so that 
the inline functions/macros are available or reimplement part of logic to 
retrieve the current task (sp masking, etc).

Are there any other options to retrieve the current task? What do you 
recommend?

Hi Thiebaud,

sorry, just realized that this fell through the cracks after vacation
back then.

I would prefer the reimplementation like we do elsewhere already.
Debugging should remain minimal invasive to the kernel.
