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.

+      Many computer users need to manipulate text files: extract and then
+      operate on data from parts of certain lines while discarding the rest,
+      make changes in various text files wherever certain patterns appear,
+      and so on.  To write a program to do these things in a language such as
+      C or Pascal is a time-consuming inconvenience that may take many lines
+      of code.  The job is easy with awk, especially the GNU implementation:
+      Gawk.
+
+      The awk utility interprets a special-purpose programming language that
+      makes it possible to handle many data-reformatting jobs with just a few
+      lines of code.
