[Buildroot] [git commit] rpcbind: allow build without NSS support

[Peter Korsgaard <jacmet@sunsite.dk>]

commit: http://git.buildroot.net/buildroot/commit/?id=1d4bc3790250d757876e42fcb78fd41fdab63707
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

uClibc doesn't provide NSS support, so we shouldn't try to include nss
related headers or call nss related functions.

+Subject: [PATCH] Do not try to use NSS support when not available in the C
+ library
+
+uClibc does not have NSS support, so it is unnecessary to tell the C
+library to use the "files" as the source for "services", since it is
+the only possible choice.
