I can see the need for it, I'm just not 100% sure I like the form of
the patch. No one particular thing is doing that, just a general
feeling of unease which I can't quite put into words :(.

We continue to have a need to differentiate between "proper" autotools
recipes and non-autotools recipes which would make this kind of issue
easier. I guess I'm trying to weigh up whether we should consider
something a bit more invasive to try and improve things and if we do
that whether this patch helps or hinders that (it probably does help).

I'm also not 100% convinced EXTRA_CONF_PACKAGECONFIG is the right name,
but I can see how you got here and I'm not sure I have a better
suggestion (PACKAGECONFIG_CONFPARAMS? _CONFARGS?)

Cheers,
