i686 Multilib Question

["Armin K." <krejzi@xxxxxxxxx>]

Hi there, this is my first post on gcc mailing lists.

I have currently i686 system (Linux From Scratch) and I would like to 
bootstrap multilib compiler on that one. The problem is, I don't have 
any working multilib compiler, only i686 one. And I don't know where to 
start.

I have tried first enabling multilib and all targets in binutils, then 
statically compiling gcc.

I ran into problems in bootstrap stage and tought it was a bug. A more 
detailed report about this can be found in bug report 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=53662

Has anyone managed to bootstrap multilib compiler using i686 one? I 
would like to have i686 compiler, but also I want to be able to use -m64 
which is done by multilib right? I am aware that I need multilib 
binutils, static gcc to compile multilib glibc and use it to bootstrap 
full gcc with shared libraries and such. Am I right? But I am unable to 
accomplish that. Could anyone guide me in right direction? Google does 
not help very much. And yes, I want this. I don't want to install or 
build 64 bit operating system.

Regards.
