We could just print something like "libnuma support: yes/no" depending on whether libnuma+numa.h are installed. It is quite common not to have libnuma installed, so having this in the summary is good. But having a very old libnuma installed without migratepages+mbind+setmempolicy should be pretty rare nowadays, so having these details in the summary shouldn't be needed. Brice
