This is a good solution for openssl, but I don't believe
that there are any more packages built in the same way
(correct me if I'm wrong on this). I think it would be better
to solve this with

ifneq ($(ISA),$(ISA_DEFAULT))

inside the openssl-Makefile and not make a general rule out
of it. A more general solution would be


with overwriting the specific install scripts on demand.
The thing that is disturbing me is the special handling of the default
ISA. In fact there are two default-ISAs: one for 32 bit and one for  
64 bit.
This makes defining the extra-ISAS a bit ugly IMHO.

This should work out-of-the-box. If the prototype is defined
in DISTFILES it shouldn't get overridden, so existing Makefiles
shouldn't break. Generally dynamic prototypes don't need adjustment
on version updates, so if there is anything missing which you need to
use them let me know what is missing and we may find a general solution.

This seems to be the same issue: dynamic prototypes. I'll make
a test environment with your openssl-Makefile and try to reproduce
