One seemingly unnecessary parameter is passed in the block parameters.

[alpha-netzilla]

In the file lib/mruby/build/command.rb, two parameters, ext and compile, are passed in the parameter of the "each" method, but the latter appears to be unnecessary.

      source_exts.each do |ext, compile|

It seems that the compile is not actually used, only ext.

I wonder if this is correct.
