What about calling these CONFIG_SSI CONFIG_STELLARIS etc. already in 
configure, and initializing them with

: ${CONFIG_SSI=n}
: ${CONFIG_STELLARIS=n}

Then you can:

1) save duplication using

for i in CONFIG_SSI CONFIG_STELLARIS; do
   case \$$i in
   if test "$config_var" = y; then
     echo "$i=y">> $config_host_mak
   fi
done

2) allow the user to force your choice by setting environment variables 
when calling configure (not sure how useful this is).

Otherwise, looks nice!
