This is an "out of interest" question rather than being particularly
important. I've managed to get my hands on an Itanium-based system for
my collection, and find that it runs the x86 Linux variant of FPC fairly
happily. However, GNU as and so on clearly don't know about x86
assembler: they expect the monstrosity that is IA-64.
I could obviously build appropriate binutils with the conventional
naming prexies, but what is the preferred way of telling FPC/PPC which
binutils to use?

Is that where the CPU_TARGET and OS_TARGET shell
variables come itno it, or are they only for use in makefiles?
http://www.stack.nl/~marcov/buildfaq/#toc-Section-1.6 point 5 in the list.
IIRC there is also a CROSSBINUTILSPREFIX in case you only have to override
it for the "cross" part.
Thanks Marco, I'd missed -XP since I was mistakenly looking at the -A
section.
For information, it works, but I'm getting an error when it calls the
linker. If I link using a script it's fine:
~$ fpc -XPi486-linux- -sh test.pas
Free Pascal Compiler version 2.6.0 [2012/05/05] for i386
Copyright (c) 1993-2011 by Florian Klaempfl and others

~$ ./ppas.sh
Linking test
/usr/local/bin/i486-linux-ld: warning: link.res contains output
sections; did you forget -T?
~$ ./test
Hello, World!
Does x86-64 on Linux provide similar emulation, and does it also require
a script for reliable operation?
