Ok, I still don't think the above is the right fix though as it still
leaves things fragile, if for example I try and enable python for gdb
by default on target.

I think we may need to do something like:

-PACKAGECONFIG[python] = "--with-python=${WORKDIR}/python,--without
-python,python,python python-codecs"
+ PACKAGECONFIG[python] = "--with-python=${WORKDIR}/python,--without
-python,python,${GDBPYTHON_RDEPENDS}"

+GDBPYTHON_RDEPENDS = "python python-codecs"

and then set:

GDBPYTHON_RDEPENDS = ""
PACKAGECONFIG += "python"

in the cross recipes.

Would that work?

Cheers,

Richard
