add new target to Binutils, why nobody reply?

[梅丽刚<ligang at sunnorth dot com dot cn>]

Hello all,

I ported Binutils to a 32 bit chip named Score and want to add it to GNU 
official.
I've done the whole process of FSF ASSIGNMENT and already placed the patch 
on Binutils maillist.
But nobody reply till now.  GCC patch for Score has been approved by GCC 
SC.
Anybody can tell me why or what should i do?  You are appreciate.
