where we don't use any tools from outside the Nix environment. For this we
need the basic POSIX utilities (e.g., GNU coreutils), a shell, GCC, and the
binutils.
Normal packages just need to include stdenv/stdenv.fix, which on Linux will
use the Nixified environment. However, for the tools in the build
environment itself we have a bootstrapping problem. Therefore, these depend
on the external environment (and include stdenv-linux/stdenv-nativetools).
The package `baseenv' provides some generic setup and GCC wrappers used by
both fully Nixified and native environments.
