Actually, in fact, in a bug-free(*) environment, it _will_ always be

* User-land programs for a given MACHINE_ARCH should not be dependent
on MACHINE at all -- any such dependence is a bug.

Given that arm32 is currently being split up, perhaps it makes sense
to make it the first guinea pig for:

	* install $(MACHINE_ARCH) includes as /usr/include/machine
	* install all of the $(MACHINE) variants in /usr/include
	* for user programs which have /usr/include/$(MACHINE)
	  dependencies, make them code for that explicitly.

Actually, the more that I think about it, the more
/usr/include/machine/$(MACHINE) makes sense to me, rather than totally
littering /usr/include with $(MACHINE)-named subdirs...
