Same as #15 just for master

Instead of having a separate scipy-native recipe, let's just use the BBCLASSEXTENDS mechanism to add the -native variant.

So you'll just add the following to the end of the python3-scipy_1.5.3.bb file:

BBCLASSEXTEND =+ "native"

You actually don't even need to redefine DEPENDS for the native recipe, because Yocto automatically appends -native to all of the values in DEPENDS when building the -native variant.

Other than that, the rest of the recipe looks identical to me.

Original native recipe doesn't build on dunfell. I fails with some strange error which was caused by some cross-compilation flags. I basically extracted it and drop one flag + setup proper DEPENDS native flags.

You can use overrides to set variables differently based on whether or not you're building the native package:

DEPENDS_class-native = "..."

FARCH = "${TUNE_CCARGS}"
FARCH_class-native = ""

export FARCH

This is preferable to having two separate recipes. There are plenty of examples of this in the poky repo and in the meta-openembedded layer.

Yes I know. I was in hurry to compile scikit-learn so this was the first shot which works. Thanks for comments I'll give a try what was suggested and post an update. 👍

@gpanders strange it seems that yesterday I have scipy-native somehow cached because today wiped out caches and it's failing. So I suggest to revert #15 or can someone test it pls? If it fails pls revert. Thanks.
