GAS does not know what format to use for target z80-unkown-none

[Terry Mackintosh <terry at mackintoshweb dot com>]

Hi

I'm trying to build a cross assembler that would be used on my laptop 
(x86_64, running Fedora Core 6) to build binaries to be run on a Z80.

At first I read the info pages, it said to use the "-z80" command line 
option with as, but that failed.

So I read some more, and it seemed likely that my stock as was not built 
to include support for the Z80?  So I downloaded the latest source of 
binutils and proceeded to install a build that did support the Z80.

There are a great deal of docs on using binutils, but there seems to be 
very little on building it.  The best I've been able to figure out is 
that when running ./configure, it needs either or both of 
--enable-targets=z80-unknown-none or --target=z80-unknown-none.

I've tried each separately and together.  --enable-targets seems to have 
no effect.  If --target is omitted, it will build but does not seem to 
have z80 support.  If --target is included it will fail when trying to 
configure gas with the message:
GAS does not know what format to use for target z80-unknown-none

I did finally figure out that the format being referred to was the 
object file format to use.  But this still leaves two questions:
A:  How does one tell configure what format to use?
B:  What is the format?


Possibly I'm missing something obvious?

Any help much appreciated.
