Of course it errors, everything in the build source is optimized to compile 
as x86 with certain optimization flags in the configs for i486. Some 
programs and libraries may not even be ported to 64 bit yet so they cannot 
be compiled at 64 bit even with the proper flags if this is the case. There 
was mention of whether there should be a 64 bit version of IPCop in the 
future. Most platforms that a firewall appliance would be run on including 
some very new expensive ones are not 64 bit. 64 bit is not even on my radar 
for a firewall appliance.   

A decade ago I remember how difficult it was for the developers of many 
Linux programs and libraries to port them over to 64 bit. Some audio 
libraries never did get ported as well as some programs. You can run a 32 
bit os on an x86_64 system and 32 bit programs on a 64 bit os with 32 bit 
compatibility libraries but that is as far as compatibility goes. To compile 
as 64 bit it has to have been ported to be able to do so. Most Windows 
programs people run in 64 bit Windows including Firefox are still 32 bit and 
nobody is the wiser. Adobe refused to port flash to 64 bit for the longest 
time and I don't know if they ever did. The one thing you absolutely cannot 
do is run 32 bit drivers in a 64 bit kernel.

If one could easily do what you tried, there'd be 64 bit IPCop iso's all 
over the internet people built. Short of going through the entire os build 
tree and changing things and hoping everything in lfs actually has 64 bit 
compatible code, at this point you have all but created your own Franken-
distro.
