build: Prevent recursive jam loops on host-only #13309 

* When --host-only is used, HAIKU_*ARCH is undefined.
* Various architecture variables are undefined resulting
  in architecture dependant code paths getting called
  recursively.
  (blah/Jamfile loads blah//Jamfile vs blah/x86/Jamfile)
* Another option is setting HAIKU_*ARCH to the host arch
  if undefined, but that might have unintended impacts.
