Like this you can build a myLib-native (for your host - x86) version and
it should be added as an x86 library to your nativesdk.

see:

Do you want myLib-native?

I guess you want something else. You want e.g. the ARM library myLib in
your sysroot plus maybe header files.

What happens if you create a recipe like a testcase for your library
which DEPENDS_append = " myLib" and then you IMAGE_INSTALL_append = "
myLib testmyLib", rebuild the image and populate_sdk?
