Eelco Dolstra 12ae5363ea * Remove trivial builders.
* Make builders unexecutable by removing the hash-bang line and
  execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
  `mkDerivation'.  These transformations were all done automatically,
  so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.

# 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.
