--- Comment #4 from Robert Clausecker <fuz@FreeBSD.org> ---
If you add this, I would like to have

 - a macro BYTEORDER which evaluates to 1234 or 4321 depending on arch
 - a macro WORDSIZE which evaluates to 32 or 64 depending on arch
 - macros {NOT,ONLY}_FOR_{32,64}{BE,LE} to conditionally enable/disable
   ports that are known to require bit/little/32 bit/64 bit architectures
