Lluís Batlle i Rossell 719ba63004 Merge branch 'stdenv-updates' into pi-stdenv-updates
Conflicts:
	pkgs/development/compilers/gcc/4.6/default.nix
	pkgs/development/compilers/gcc/4.7/default.nix

The 4.7 had some weird parameters added in crossAttrs; I've removed
them, but I don't understand where they come from.

# This file defines the various standard build environments.
#
# On Linux systems, the standard build environment consists of
# Nix-built instances glibc and the `standard' Unix tools, i.e., the
# Posix utilities, the GNU C compiler, and so on. On other systems,
# we use the native C library.
# stdenvType exists to support multiple kinds of stdenvs on the same
# system, e.g., cygwin and mingw builds on i686-cygwin. Most people
# can ignore it.
