Add a line for the native variant so you get:

EXTERNALSRC_pn-myrecipe = path_x
EXTERNALSRC_pn-myrecipe-native = path_x

Note that this will only work if S != B in your recipe, otherwise you
will probably end up with a mishmash of object files of different
architectures.

If you do use different checkouts

EXTERNALSRC_pn-myrecipe = path_x
EXTERNALSRC_pn-myrecipe-native = path_y

will work for S==B, but then you will have to extract the sources some
other way. devtool extract may work here, but I have not tested myself.
