Patch so that linecache gem actually works

For -2:

* %define -> %global
  - Still %define is used in the first line.

* BR
  - "BuildRequires: rubygem(rake)" is needed for
    "rake test".

* %{geminstdir}/ext
  - I don't think this directory is needed and should completely
    be removed.
    ! Note
      - To avoid trace_nums.so regeneration in %check, rake test should
        be done under %_builddir%geminstdir, not under
        %buildroot%geminstdir

* Usability

-------------------------------------------------------------
  - i.e. Currently the installed linecache gem does not work.
    This is because we move trace_nums.so from %geminstdir/ext to
%ruby_sitearch.
    The attached patch (for example) is needed (on Fedora).
