Tweaks of GCC 4.8.

* Remove obsolete ENV.m64. Configure will detect host triplets.
* Don't unset __GLIBCXX_DEBUG* as the original bug entry didn't actually
  suggest that.
* Make arch and osmajor standalone functions, and construct host triplet
  for build.
* Integrate '--enable-languages' into args.
* Make free functions into class.

Closes #106.

More tweaks for gcc43.

* Pass build flags to make instead of patching Makefile.in.
  - This is non-intrusive, and the canonical way to pass build flags.
Set arch according to CPU type and bits.

* Thanks @mistydemeo for the suggestion.

Closes #112.
