Currently, I get:

NOTE: There are 10 recipes to be removed from the sysroot, removing...
NOTE: There are 15 recipes to be removed from the sysroot, removing...
NOTE: There are 30 recipes to be removed from the sysroot, removing...

Can we print more info such as where it is removing, please ? Or
use SSTATE_ARCHS ? For example,:

NOTE: There are 30 recipes to be removed from manifest x86_64, removing...
