I am not against flexibility here. What I don't like
is the special meaning of ISA_DEFAULT here. You have
a custom installer, which you could call simply by
overriding the generic installer in your Makefile:

   install-isa-pentium_pro install-isa-amd64: install-isa

If there really is need for the special case I'd like
this to be handled in a more general way working for
all ISAs, not only ISA_DEFAULT.

Best regards
