On compiling for x86_64 on an i386...

[maze at cela.pl (Maciej Żenczykowski)]

Hi folks,

Anyway, I have a main development system which is P4 based (without EM64T) 
and a dozen diskless Athlon 64's.  I'd like to be able to compile 
kernel's, etc for the Athlons in x86_64 bit mode.  Any idea how to arrange 
this?

I've recompiled the src.rpm for binutils (added a single line 
"CARGS=--enable-targets=x86_64-linux" to the specfile)
and "as --64" doesn't bork anymore, so I'm assuming I've got that right...

I'm assuming I next have to do something to gcc?  Haven't figured this out 
yet... Anything else needed?

Holiday cheers,
MaZe.
