Lluís Batlle i Rossell 4b27d28701 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.
