That sequence is correct.

I think you'll need to get a bit forensic on the error logs.  The build 
scripts emit config and make logs in the ./build/bld_gcc/*_log subdirs.

Take a look, see if you can find the offending invokation of mb-linux-as 
with the -Qy option.  Re-run that from the command line, make sure it's 
the same error.  Try rerunning without that option, see what happens.

I'll try to dig out my build logs see if I can see whether your problem is

(a) your binutls is failing to accept -Qy when it should, or
(b) gcc's build is erroneously specifying this option.

This stuff is all part of why I hate building gcc.  Life is better when 
I can pretend it is a binary blob that just works.

Cheers,

John
