prologue/standards: rewrite LSB description

Well, somehow this paragraph has become too imprecise.

1. We don't support IA64.  Both Intel and AMD uses x86_64 now, which is
   referred as "AMD64" because it's first proposed by AMD.  Intel
   attempted to use IA64 (which is a VLIW architecture completely
   different with x86_64) to compete with AMD64, but failed.  Then Intel
   adapted x86_64.
2. The architecture specific part belongs to Core and Desktop.
3. LFS cannot conform to both AMD64 and IA32 because we don't support
   multilib.  It's "or", not "and".
