Eelco Dolstra 01a1658c6b * Finally we have a working stdenvLinux again.
On the downside, the build process of stdenvLinux builds gcc 9 times
  (3 x 3 bootstrap stages).  That's a bit excessive.

# The Nix `gcc' stdenv.mkDerivation is not directly usable, since it doesn't
# know where the C library and standard header files are. Therefore
# the compiler produced by that package cannot be installed directly
# in a user environment and used from the command line. This
# stdenv.mkDerivation provides a wrapper that sets up the right environment
# variables so that the compiler and the linker just "work".
