Lluís Batlle i Rossell 7ade207f6b - Removed all *NoCross expressions I dupilcated in nixpkgs, while maintaining
the cross compilation functionality.
- I renamed some expected stdenv.mkDerivation parameter attributes so we can
  keep this branch properly updated from trunk. We agreed with Nicolas Pierron
  doing a massive renaming, so all current buildInputs become hostInputs (input
  as build for the host machine, in autotools terminology) , and
  then buildInputs would mean "input as for the build machine".
  By now, the specific "input as for the build machine" is specified through
  buildNativeInputs. We should fix this in the merge to trunk.
- I made the generic stdenv understand the buildNativeInputs, otherwise if
  we start changing nixpkgs expressions so they distinguish the current
  buildInputs into buildInputs and buildNativeInputs, we could break even more
  nixpkgs for other platforms.
- I changed the default result of mkDerivation so it becomes the derivation for
  to be run in the build machine. This allows, without any special rewriting,
  "fetchurl" derivations to be always results for the build machine to use
  them.
- The change above implies that, for anyone wanting to cross-compile, has to
  build the hostDrv of the wanted derivation. For example, after this commit,
  the usual test of "nix-build -A bison.hostDrv arm.nix" works. I described
  the contents of this arm.nix in r18398.

description = "GNU Bison, a Yacc-compatible parser generator";
longDescription = ''
Bison is a general-purpose parser generator that converts an
annotated context-free grammar into an LALR(1) or GLR parser for
that grammar. Once you are proficient with Bison, you can use
it to develop a wide range of language parsers, from those used
in simple desk calculators to complex programming languages.
Bison is upward compatible with Yacc: all properly-written Yacc
grammars ought to work with Bison with no change. Anyone
familiar with Yacc should be able to use Bison with little
trouble. You need to be fluent in C or C++ programming in order
to use Bison.
