[Ironruby-core] IronRuby's rake script with MRI versions greater than 1.8.6

[Daniele Alessandri]

Hello,

I just uploaded a gist on GitHub with a quick fix that allows
IronRuby's rake script to also run on versions of the MRI greater than
1.8.6 (actually tested with "rake compile" on 1.8.6p383 and
1.9.1p376). Here is the .diff:

PS: on a totally unrelated and side note, mono's gmcs 2.6.1 breaks
when compiling IronRuby after the last commit on the Git repository :(
