I don't think the default of the dynamic linker name etc. (which should go
on https://sourceware.org/glibc/wiki/ABIList) belong in the NEWS entry.

I think the wiki should be updated at the time the port is committed.
https://sourceware.org/glibc/wiki/NewPorts lists all the wiki pages that
should be updated (MAINTAINERS, ABIList, PortStatus, Release/X.Y and the
copy for the next release).
