Porting changes from stdenv-updates into this branch.

This comes from:
svn diff  ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.

trunk@18255 comes from the last time I updated stdenv-updates from trunk.


svn path=/nixpkgs/stdenv-updates2/; revision=18272

pkgs/development/libraries/readline/link-against-ncurses.patch

@@ -0,0 +1,18 @@
+This patch is to make sure that `libncurses' is among the `NEEDED'
+dependencies of `libreadline.so' and `libhistory.so'.
+
+Failing to do that, applications linking against Readline are
+forced to explicitly link against libncurses as well; in addition,
+this trick doesn't work when using GNU ld's `--as-needed'.
