[Buildroot] [PATCHv3 2/5] core: allow external Config.in/makefile code to be integrated

[Jeremy Rosen <jeremy.rosen@openwide.fr>]

Just an overall comment, this patch serie is great, it will help us 
a lot

by allowing us to clearly show to our customers what is specific 
to their board and what is changes to the buildroot unfrastructure
it will make it much easier for us to upstream all the non-specific 
parts


on this particular one, if I remember correctly the kconfig infrastructure
will not work correctly if one of the include is missing... so shouldn't
your infrastructure check if $(BR2_EXTERNAL)/package/Config.in 
exists, and create one if it doesn't ?
