- skip the non-packagegroup allarch recipes in multilib_virtclass_handler
- extend PROVIDES/RPROVIDES for allarch recipes which are not packagegroups
- use variants from MULTILIB_GLOBAL_VARIANTS (lib32 lib64 libx32) to create
additional pkgdata files for multilib allarch: ${pkgdatadir}/${variant}-${PN}
and ${pkgdatadir}/runtime/${variant}-${pkg}
- use variants from MULTILIB_VARIANTS to create additional pkgdata files
for multilib kernel/module-base recipes
- add a sanity check to determine if the current multilib is in
MULTILIB_GLOBAL_VARIANTS
