autotools.bbclass will assume it's a target package if the name doesn't
end with -native or starts with -nativesdk (kind of a catch-all), so
target packages should be fine.

I think autotools.bbclass::autotools_copy_aclocals() can be patched to use
bb.data.inherits_class() to detect native and nativesdk packages (and so
will not need to look at the package name), but I still feel like this is
a good patch for meta-java since a -native prefix seem to be more or less
package name convention.
