native/nativesdk: Stop overriding unprefixed *FLAGS variables

We're currently encouraging an "arms race" with the FLAGS variables since
a recipe might want to set a specific flag for all variants but to do so,
+= won't work due to the assignment in the native/nativesdk class files. This
means recipes are using append.

Since the default variables are constructed out of TARGET_XXX variables and
we redefine these, there is no need to re-define the un-prefixed variables. If
we drop that, the += appends and similar work and recipes don't have to resort
to append.

Change the classes and cleanup a number of recipes to adapt to the change. This
change will result in some flags appearing to some native/nativesdk variants
but that is probably what was originally expected anyway.
