I also endorse this in principle.  As with the sunrpc patch, a diff of
installation trees would be helpful to reviewers.

There are a lot of configure scripts out there that do
AC_CHECK_LIB([nsl], [gethostbyname]).  Yes, that should be
AC_SEARCH_LIBS, the Autoconf manual even says so these days, but some
people are still using autoconf 2.13, so.  Would you please verify
that an autoconf script with AC_CHECK_LIB([nsl], [gethostbyname]) in
it does _not_ fail when run against a glibc with this modification,
and the generated makefile does _not_ try to link -lnsl?

The NEWS entry should explain which programs are likely to need your
libnsl replacement.  It's my impression that the answer is "almost
none", but it's important to be reassuring here.
