AFAIK there is no such list, however as soon as you use  
AC_CANONICAL_HOST in configure.ac *and* you use automake, automake  
will install config.sub and config.guess.  The role of config.sub is  
to validate and canonicalize a given --host whereas the role of  
config.guess is to guess a canonical system name.

# Find the canonical name of mingw32
$ ./config.sub mingw32
i386-pc-mingw32

# Find the canonical name of my system
$ ./config.guess
i386-apple-darwin8.10.1

By looking at the switch-case done by these scripts, you can figure  
out the various hosts recognized by --host.

By the way, I have a question to the list, AC_CANONICAL_HOST implies  
AC_CANONICAL_BUILD, maybe this should be mentionned in the  
documentation?  Also, is it normal that I absolutely need to use  
automake in order to use AC_CANONICAL_*?  Actually, as soon as you  
use AC_CANONICAL_*, configure will require install-sh, which is  
installed by automake.  Thus you have to use AM_INIT_AUTOMAKE and at  
least add an empty Makefile.am and use AC_CONFIG_FILES([Makefile]).
