I think info like that would already be available in autoconf, I'd have 
to do a bit of searching in the docs but I'd be happy to look it up for 
you. We currently only distinguish between 'host' and 'build ' using 
autoconf, but we could also support 'target'. From the autoconf info page:

|--build=build-type|
    the type of system on which the package is being configured and
    compiled (rarely needed); 
|--host=host-type|
    the type of system on which the package will run; 
|--target=target-type|
    the type of system for which any compiler tools in the package will
    produce code.

What exactly isn't working portably in heimdal at the moment?

Cheers,
