distro: Bootstrap with a joint GCC/Binutils/GMP/MPFR/MPC build.

Browse source 
* distro/base.scm (%bootstrap-inputs): Remove GMP, MPFR, and MPC.
  (substitute-keyword-arguments): New macro.
  (gcc-boot0): Add dependency on the Binutils, GMP, MPFR, and MPC
  tarballs.  Add a `unpack-binutils&co' phase to unpack them and symlink
  them so they get built, and to patch errors in `configure'.
  (glibc-final): Use `substitute-keyword-arguments' instead of a loop.
  (gcc-final): Inherit from GCC-4.7 instead of GCC-BOOT0.
