  DejaGnu supports a "Global site.exp" file, that is basically a big
case statement. You can set target_list to the list of board names, and
then use the same tool chain and target triplet for all the tests. At one
point at Cygnus, we had a global config file that supported many dozens of
different target boards.

  There is an example one at gcc/contrib/regression/site.exp that reads:

global target_list
 
case "$target_triplet" in {
    { "powerpc*-*eabi*" } {
#       if { [info exists tool] && $tool == "gcc" } {
#           set target_list { "powerpc-sim{,-fpic}" }
#       } else {
            set target_list { "powerpc-sim" }
#       }
    }
    { "mips*-*-elf" } {
        set target_list { "mips-sim" }
    }
 
    default {
        set target_list { "unix" }
    }
}

  You can put pretty much any Tcl code you want in this file. This should also
be covered in the manual.
