Those 2 errors were red herrings that got me by looking for where things first went wrong. These 2 errors appear the way Arch build gcc, even on 8.2.1. They're not fatal errors. Per the revision's comments, "make... install-gnatlib" just needed to be changed to "make... install-libada". This command comes just after the "make ada-install-{common,info}" which is what threw me.
