There must never be any installed headers specific to x86_64 or i386, 
because headers installed for one multilib configuration may be used for 
all three.  Thus, you need a single header for x86, and if there are any 
differences between x86_64 (64-bit), x86_64 (x32) and i386, that header 
must contain appropriate conditionals.
