I'm not sure that we want our own-build host-python... You may want to use some
of the system's python packages, for example. So I think it is better to drop
the host-python dependency, and use the system python instead. (Note that python
is a dependency of buildroot.)

Huh? We are talking about the host-gdb here, so why do you need a target python?
One more thing: on AVR we still use gdb 6.7 which doesn't have python support,
so something must be done to catch that.
