+Subject: [PATCH] remove libnsl
+
+glibc now considers its built-in libnsl as being obsolete, and requires
+passing --enable-obsolete-libnsl to have it built and installed. libnsl
+is now provided as a separate project [1], but it isn't packaged yet in
+Buildroot.
+
+Exim's nis.so and nisplus.so lookup modules require libnsl,
+but they are not build by default. So we can safely remove -lnsl
+from the Makefile-Linux.
