Eelco Dolstra 48ac8018ca Improved support for building 32-bit binaries on x86_64-linux.
* glibc_multi: a wrapper that combines the 32-bit and 64-bit Glibcs.
  This is necessary so that 64-bit GCC can find gnu/stubs-32.h and the
  32-bit Glibc libraries.

  To build glibc_multi on x86_64-linux, you still need either the
  i686-linux Glibc derivation from a channel, or to have configured
  Nix with support for forwarding the build to a i686-linux machine.
  In the future this may become unnecessary by providing a prebuilt
  binary of 32-bit Glibc somewhere (like the binaries used in the
  stdenvLinux bootstrap).

* With glibc_multi, it becomes possible to build gcc with multilib
  support (i.e. it builds 32-bit and 64-bit versions of libgcc,
  libstdc++, etc.).
