Take a real world testcase where you have two recipes, each of which contains PACKAGES_DYNAMIC = "gdk-pixbuf-loaders-*" and recipes which RDEPEND on some gdk-pixbuf-loaders-xxx package. To select between these you need to set a PREFERRED_PROVIDER. These are specified in the PN namespace so the locgical conclusion is that setting PREFERRED_PROVIDER_gdk-pixbuf = "gtk+" should work. It doesn't and instead checks crazy things. The code was correctly finding the two possible providers, gtk+ and gdk-pixbuf. It was however only accepting PREFERRED_PROVIDER_gtk+ = "gdk-pixbuf" to resolve this problem which reads as the exact opposite to what was wanted. This patch changes the code to do something that makes sense. I suspect that before these changes it was pretty much a null operation rubber stamping the single provider case. For Poky at least it exposes a few cases where -nativesdk recipes were providing the same things as their normal counterparts but these are genuine bugs in the metadata. I've also attempted to make the multiple provider error message human readable as I counldn't understand it and I doubt anyone else could either.
