[Buildroot] binutils doesn't like -elf2flt option

I'm not entirely sure.  I can run "make binutils" to cause the error, so I'm 
assuming it must be target binutils.  But then that doesn't make sense, 
because I have not configured buildroot to compile binutils for my target 
platform (BR2_PACKAGE_BINUTILS=n).

There is a file buildroot/build/host-binutils-2.23.2/.stamp_built so I am 
guessing that means the cross binutils worked.  So I am not sure why it is 
trying to compile target binutils?

Here's my buildroot config if it helps: 
<http://www.shikadi.net/files/buildroot/2013-06-17.br.binutils_elf2flt_err.config>

Be warned there are a couple of new options in there I have added myself.

Hmm yes, since I'm not producing BFLT binaries (as they will run on the host) 
I can see that I should not be specifying these options.  However since the 
host/cross binutils builds successfully, it seems that part is working.

Would this mean elf2flt gets built before the target binutils, should I choose 
to enable it?  I am guessing that is what needs to happen for this to work 
correctly, assuming target binutils should be built.

Many thanks,
Adam.
