That works if we can't just make the top-level Makefile set $(dst) for
itself. Which perhaps we could, if we stopped it running the whole
recursive installation on include/ for each arch, and instead made it
run only on include/asm-$(ARCH) for each arch.

And do a separate run for the other directories, of course -- probably
with $(ARCH) and $(SRCARCH) set to empty or something.

That also might help shave a little more time off by not repeating the
export 20 times for every non-asm subdirectory. (Not that we actually
_do_ repeat it, but even the make invocation and the dependency checks
take time).
