Hello :-)

binutils doesn't come with GCC directly (although I think you can add it to 
the sources and build it at the same time).

You need binutils 2.12 or 2.13 for the combreloc stuff that obviates the need 
for objprelink-ing. There's not much difference between the two so don't 
bother upgrading to 2.13 if you've already got 2.12.
'ld -version' is your friend :-)

There's some info on combreloc/objprelink at the objprelink site
http://objprelink.sourceforge.net/

Binutils home page is either http://www.gnu.org/software/binutils/ (which 
still has 2.12 as the current version) or http://sources.redhat.com/binutils/ 
(which mentions 2.13)

There's an interesting Linux From Scratch hint at
http://hints.linuxfromscratch.org/hints/combreloc.txt
which details a simple script front-end to ld that ensures everything linked 
gets passed the '-z combreloc' flag.

There's also a very simple patch which can be applied to the ld sources 
themselves to the same effect (just change one variable from 'false' to 
'true'). That's also mentioned over at LFS
http://archive.linuxfromscratch.org/mail-archives/blfs-dev/2002/07/0094.html

To be perfectly honest, I haven't tried any of this stuff yet myself, (but I 
will be doing so next week), so don't blame mean if the above blows up your 
computer :-)
If anyone out there has already been through the loop, I'd appreciate more 
details as well please.

P.S. Don't forget to google on 'combreloc' for more info.

Cheers,
Sean
