The usual way to use autoconf is to *NOT* try to do things based on the name of 
the "canonical host", but instead, identify specific feature sets and figure 
out how to get them.  That way, if version "X" doesn't have the feature but 
version "Y" does, you're okay.  For example, there are lots of variations 
between linux systems... your users will more likely have success if you look 
for the specific features.

You mention you're new to the autotools. You might try out this short intro 
tutorial that I created:
It's only an intro, so it won't answer every question, but it might help you 
get started.
