Re: [Consult] About tool chains of metag

Thank you very much for your details valuable information.

I will/should try my best to let it pass allmodconfig, and I guess
https://lkml.kernel.org/r/201211161520.03974.arnd-r2nGTMty4D4@public.gmane.org is valuable
to me, and I will/should reference it.

I will/should try to finish allmodconfig within one month, but excuse
me, I have to do it in my free time as a volunteer, so maybe it needs
longer (but at least, it should be finished within 2014-1-31).

Thanks.
