configure detects which set of prebuilt binaries to use

Browse source 
* configure.ac: Use detected endianness and word size to automatically
  select which set of prebuilt binaries to use.
* meta/build-env.in (top_builddir):
* meta/uninstalled-env.in (top_builddir): Update to use
  SCM_PREBUILT_BINARIES for prebuilt entry in GUILE_LOAD_COMPILED_PATH.
* prebuilt/32-bit-big-endian:
* prebuilt/32-bit-little-endian:
* prebuilt/64-bit-little-endian: New links.
* prebuilt/x86_64-pc-linux-gnu: Remove this link now that it's unneeded.
