If we merge new ports for glibc 2.32, it would be nice not include
sunrpc in them.  We'll figure something out.

Sorry, no change to the patch is required.  Removing this is fine.  We
shouldn't have had a default that depends on LINK_OBSOLETE_NSL.

nss_compat no longer depends on libnsl in current glibc.  It can be used
without NIS, and some users do that.  I don't think your patch changes
this.

Thanks,
