The actual difference in the profile itself? Just a make.defaults file 
with 'MULTILIB_ABIS="amd64"' (and the usual parent file).

I'm not very experienced with this either, just that I had troubles 
bootstrapping with multilib (Under Debian Etch AMD64 - I realize now 
that it's probably because I didn't have Debian's libc6-dev-i386 package 
installed at the time). But then again, I only really want a pure x84_64 
prefix - I'm not planning to run pre-compiled 32-bit software with my 
prefix :)

The main problem is that I can't get GCC to compile using the multilib 
profile:

Adding my own no-multilib profile (which ensures that GCC gets 
configured with "--disable-multilib") fixes this.
