in our autotools project, we are using AC_CANONICAL_HOST to determine the host architecture/OS/... via the host (resp host_cpu, host_os and host_vendor) variable(s).
Traditionally this involves (at least for us) to configure on real installations of the actual host, see what values we get and adjust our logic to do the right thing™.
Now it's obviously a bit awkward for having to check these values on real (or virtualized) systems.
Is there some list of canonical output of the AC_CANONICAL_* macros?
