Thorsten Kukuk 1e4d83f6fe Deprecate libnsl by default (only shared library will be
build for backward compatibility, no linking possible) and disable building
of libnss_compat, libnss_nis and libnss_nisplus, except --enable-obsolete-nsl
option is given to configure.

        * config.h.in: Add LINK_OBSOLETE_NSL.
        * config.make.in: Add build-obsolete-nsl.
        * configure.ac: Add obsolete-nsl option.
        * include/libc-symbols.h: Define libnsl_hidden_nolink_def.
        * include/rpcsvc/yp.h: Add missing functions as libnsl_hidden_proto.
        * include/rpcsvc/nislib.h: Likewise.
        * include/rpcsvc/ypclnt.h: Likewise.
        * manual/install.texi: Document --enable-obsolete-nsl.
        * nis/Makefile: Build only libnsl by default (add build-obsolete-nsl).
        * nis/nis_add.c: Replace libnsl_hidden_def with
        libnsl_hidden_nolink_def.
        * nis/nis_addmember.c: Likewise.
        * nis/nis_call.c: Likewise.
