unrecognized option '-mcpu=r4600'

[Xu, Jiang]

Though I am new to cross compiling, if you try to build binutils-2.14.90.0.5
and run "as --help", you saw "-mCPU", NOT "-mcpu".  However, as in the
message I sent last time, I think this paticular version does not support
"-mcpu".  I think this is the reason why "-mcpu" is recognized by cc1, not
as.

sorry if i came as a grumpy sort of person, but i think it's important 
to do your own personal research before asking the obvious. i'd hate to 
be the person who, for example, joins Linux kernel hackers mailing list 
and then asks things like "So what is Linux anyway?"
